VAR-201805-0950
Vulnerability from variot - Updated: 2026-04-10 22:40A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs. In some circumstances, some operating systems or hypervisors may not expect or properly handle an Intel architecture hardware debug exception. Microsoft Windows is prone to a local privilege-escalation vulnerability. An attacker can exploit this issue to execute arbitrary code with elevated privileges. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

-- RHSA-announce mailing list RHSA-announce@redhat.com https://www.redhat.com/mailman/listinfo/rhsa-announce . These CVEs are both related to the way that the linux kernel handles certain interrupt and exception instructions. The issue can be triggered by an unprivileged user.
The fix for this problem requires modification of the interrupt descriptor tables (IDT), and modification of the interrupt handlers. Livepatch is unable to safely modify these areas, so upgrading to a corrected kernel and rebooting is required to fix the problem.

linux, linux-lts-trusty vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 ESM
Summary:
Several security issues were fixed in the Linux kernel. This update provides the corresponding updates for Ubuntu 12.04 ESM. A local attacker could use this to cause a denial of service (system crash). This issue only affected the amd64 architecture. A local attacker in a KVM virtual machine could use this to cause a denial of service (guest VM crash) or possibly escalate privileges inside of the virtual machine. This issue only affected the i386 and amd64 architectures. (CVE-2018-1087)
Andy Lutomirski discovered that the Linux kernel did not properly perform error handling on virtualized debug registers. (CVE-2018-1000199)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 ESM: linux-image-3.13.0-147-generic 3.13.0-147.196~precise1 linux-image-3.13.0-147-generic-lpae 3.13.0-147.196~precise1 linux-image-3.2.0-134-generic 3.2.0-134.180 linux-image-3.2.0-134-generic-pae 3.2.0-134.180 linux-image-3.2.0-134-highbank 3.2.0-134.180 linux-image-3.2.0-134-omap 3.2.0-134.180 linux-image-3.2.0-134-powerpc-smp 3.2.0-134.180 linux-image-3.2.0-134-powerpc64-smp 3.2.0-134.180 linux-image-3.2.0-134-virtual 3.2.0-134.180 linux-image-generic 3.2.0.134.149 linux-image-generic-lpae-lts-trusty 3.13.0.147.138 linux-image-generic-lts-trusty 3.13.0.147.138 linux-image-generic-pae 3.2.0.134.149 linux-image-highbank 3.2.0.134.149 linux-image-omap 3.2.0.134.149 linux-image-powerpc 3.2.0.134.149 linux-image-powerpc-smp 3.2.0.134.149 linux-image-powerpc64-smp 3.2.0.134.149
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. Summary:
Updated redhat-virtualization-host packages that fix several bugs and add various enhancements are now available. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.
Includes GlusterFS fixes for CVE-2018-1088, dhcp fixes for CVE-2018-1111, kernel fixes for CVE-2018-1087, and kernel fixes for CVE-2018-8897.

Topic: Mishandling of x86 debug exceptions
Category: core Module: kernel Announced: 2018-05-08 Credits: Nick Peterson, Everdox Tech LLC https://www.linkedin.com/in/everdox Andy Lutomirski Affects: All supported versions of FreeBSD. Corrected: 2018-05-08 17:03:33 UTC (stable/11, 11.2-PRERELEASE) 2018-05-08 17:12:10 UTC (releng/11.1, 11.1-RELEASE-p10) 2018-05-08 17:05:39 UTC (stable/10, 10.4-STABLE) 2018-05-08 17:12:10 UTC (releng/10.4, 10.4-RELEASE-p9) CVE Name: CVE-2018-8897
For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit . Background
On x86 architecture systems, the stack is represented by the combination of a stack segment and a stack pointer, which must remain in sync for proper operation. Instructions related to manipulating the stack segment have special handling to facilitate consistency with changes to the stack pointer.
II. If that instruction is a system call or similar instruction that transfers control to the operating system, the debug exception will be handled in the kernel context instead of the user context.
III. Impact
An authenticated local attacker may be able to read sensitive data in kernel memory, control low-level operating system functions, or may panic the system.
IV. Workaround
No workaround is available.
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, using either a binary or source code patch, and then reboot.
1) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility:
freebsd-update fetch
freebsd-update install
And reboot.
2) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.
[FreeBSD 11.1]
fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.11.1.patch
fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.11.1.patch.asc
gpg --verify debugreg.11.1.patch.asc
[FreeBSD 10.4]
fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.10.4.patch
fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.10.4.patch.asc
gpg --verify debugreg.10.4.patch.asc
b) Apply the patch. Execute the following commands as root:
cd /usr/src
patch < /path/to/patch
c) Recompile and install your kernel as described in and reboot the system.
VI. Correction details
The following list contains the correction revision numbers for each affected branch.
Branch/path Revision
stable/10/ r333370 releng/10.4/ r333371 stable/11/ r333369 releng/11.1/ r333371
To see which files were modified by a particular revision, run the following command, replacing NNNNNN with the revision number, on a machine with Subversion installed:
svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base
Or visit the following URL, replacing NNNNNN with the revision number:
VII. 6.7) - i386, ppc64, s390x, x86_64
Bug Fix(es):
-
The kernel build requirements have been updated to the GNU Compiler Collection (GCC) compiler version that has the support for Retpolines. The Retpolines mechanism is a software construct that leverages specific knowledge of the underlying hardware to mitigate the branch target injection, also known as Spectre variant 2 vulnerability described in CVE-2017-5715. (BZ#1554253)

"data": "A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer\u0027s Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL \u003c 3, the debug exception is delivered after the transfer to CPL \u003c 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs. In some circumstances, some operating systems or hypervisors may not expect or properly handle an Intel architecture hardware debug exception. Microsoft Windows is prone to a local privilege-escalation vulnerability. \nAn attacker can exploit this issue to execute arbitrary code with elevated privileges. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: kernel security update\nAdvisory ID: RHSA-2018:1347-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2018:1347\nIssue date: 2018-05-08\nCVE Names: CVE-2018-1087 CVE-2018-8897 CVE-2018-1000199 \n=====================================================================\n\n1.

This update provides the\ncorresponding updates for Ubuntu 12.04 ESM. A local attacker\ncould use this to cause a denial of service (system crash). This issue only\naffected the amd64 architecture. A local attacker in a KVM virtual machine could use this to\ncause a denial of service (guest VM crash) or possibly escalate privileges\ninside of the virtual machine. This issue only affected the i386 and amd64\narchitectures. (CVE-2018-1087)\n\nAndy Lutomirski discovered that the Linux kernel did not properly perform\nerror handling on virtualized debug registers. (CVE-2018-1000199)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 12.04 ESM:\n linux-image-3.13.0-147-generic 3.13.0-147.196~precise1\n linux-image-3.13.0-147-generic-lpae 3.13.0-147.196~precise1\n linux-image-3.2.0-134-generic 3.2.0-134.180\n linux-image-3.2.0-134-generic-pae 3.2.0-134.180\n linux-image-3.2.0-134-highbank 3.2.0-134.180\n linux-image-3.2.0-134-omap 3.2.0-134.180\n linux-image-3.2.0-134-powerpc-smp 3.2.0-134.180\n linux-image-3.2.0-134-powerpc64-smp 3.2.0-134.180\n linux-image-3.2.0-134-virtual 3.2.0-134.180\n linux-image-generic 3.2.0.134.149\n linux-image-generic-lpae-lts-trusty 3.13.0.147.138\n linux-image-generic-lts-trusty 3.13.0.147.138\n linux-image-generic-pae 3.2.0.134.149\n linux-image-highbank 3.2.0.134.149\n linux-image-omap 3.2.0.134.149\n linux-image-powerpc 3.2.0.134.149\n linux-image-powerpc-smp 3.2.0.134.149\n linux-image-powerpc64-smp 3.2.0.134.149\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. Summary:\n\nUpdated redhat-virtualization-host packages that fix several bugs and add\nvarious enhancements are now available. These packages include redhat-release-virtualization-host,\novirt-node, and rhev-hypervisor. RHVH features a Cockpit user\ninterface for monitoring the host\u0027s resources and performing administrative\ntasks. \n\nIncludes GlusterFS fixes for CVE-2018-1088, dhcp fixes for CVE-2018-1111,\nkernel fixes for CVE-2018-1087, and kernel fixes for CVE-2018-8897. \n\nA list of bugs fixed in this update is available in the Technical Notes\nbook:\nhttps://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/ht\nml/technical_notes/\n\n4.

Background\n\nOn x86 architecture systems, the stack is represented by the combination of\na stack segment and a stack pointer, which must remain in sync for proper\noperation. Instructions related to manipulating the stack segment have\nspecial handling to facilitate consistency with changes to the stack pointer. \n\nII. If that instruction is\na system call or similar instruction that transfers control to the operating\nsystem, the debug exception will be handled in the kernel context instead of\nthe user context. \n\nIII. Impact\n\nAn authenticated local attacker may be able to read sensitive data in kernel\nmemory, control low-level operating system functions, or may panic the\nsystem. \n\nIV. Workaround\n\nNo workaround is available. \n\nV. Solution\n\nUpgrade your vulnerable system to a supported FreeBSD stable or\nrelease / security branch (releng) dated after the correction date,\nusing either a binary or source code patch, and then reboot. \n\n1) To update your vulnerable system via a binary patch:\n\nSystems running a RELEASE version of FreeBSD on the i386 or amd64\nplatforms can be updated via the freebsd-update(8) utility:\n\n# freebsd-update fetch\n# freebsd-update install\n\nAnd reboot. \n\n2) To update your vulnerable system via a source code patch:\n\nThe following patches have been verified to apply to the applicable\nFreeBSD release branches. \n\na) Download the relevant patch from the location below, and verify the\ndetached PGP signature using your PGP utility. \n\n[FreeBSD 11.1]\n# fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.11.1.patch\n# fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.11.1.patch.asc\n# gpg --verify debugreg.11.1.patch.asc\n\n[FreeBSD 10.4]\n# fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.10.4.patch\n# fetch https://security.FreeBSD.org/patches/SA-18:06/debugreg.10.4.patch.asc\n# gpg --verify debugreg.10.4.patch.asc\n\nb) Apply the patch. Execute the following commands as root:\n\n# cd /usr/src\n# patch \u003c /path/to/patch\n\nc) Recompile and install your kernel as described in\n\u003cURL:https://www.FreeBSD.org/handbook/kernelconfig.html\u003e and reboot the\nsystem. \n\nVI. Correction details\n\nThe following list contains the correction revision numbers for each\naffected branch. \n\nBranch/path Revision\n- -------------------------------------------------------------------------\nstable/10/ r333370\nreleng/10.4/ r333371\nstable/11/ r333369\nreleng/11.1/ r333371\n- -------------------------------------------------------------------------\n\nTo see which files were modified by a particular revision, run the\nfollowing command, replacing NNNNNN with the revision number, on a\nmachine with Subversion installed:\n\n# svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base\n\nOr visit the following URL, replacing NNNNNN with the revision number:\n\n\u003cURL:https://svnweb.freebsd.org/base?view=revision\u0026revision=NNNNNN\u003e\n\nVII. 6.7) - i386, ppc64, s390x, x86_64\n\n3. \n\nBug Fix(es):\n\n* The kernel build requirements have been updated to the GNU Compiler\nCollection (GCC) compiler version that has the support for Retpolines. The\nRetpolines mechanism is a software construct that leverages specific\nknowledge of the underlying hardware to mitigate the branch target\ninjection, also known as Spectre variant 2 vulnerability described in\nCVE-2017-5715.

Title
Arbitrary Memory read in BPF Linux Kernel
Summary
There exists an arbitrary memory read within the Linux Kernel BPF - Constants provided to fill pointers in structs passed in to bpf_sys_bpf are not verified and can point anywhere, including memory not owned by BPF. An attacker with CAP_BPF can arbitrarily read memory from anywhere on the system. We recommend upgrading past commit 86f44fcec22c

Title
Linux Kernel LoadPin bypass via dm-verity table reload
Summary
Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5

Title
Use-after-free in io_uring ad work_flags in Linux Kernel
Summary
io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859

Improper memory handling in Linux KVM
Summary
An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation.

Title
Linux Kernel sctp_destroy_sock race condition
Summary
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
Severity
6.7 (Medium)
CWE
- CWE-362 - Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization)

Title
Unprivileged overlay + shiftfs read access
Summary
Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef ("ovl: stack file ops"). This was fixed in kernel version 5.8 by commits 56230d9 ("ovl: verify permissions in ovl_path_open()"), 48bd024 ("ovl: switch to mounter creds in readdir") and 05acefb ("ovl: check permission to open real file"). Additionally, commits 130fdbc ("ovl: pass correct flags for opening real directory") and 292f902 ("ovl: call secutiry hook in ovl_real_ioctl()") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da ("ovl: do not fail because of O_NOATIMEi") in kernel 5.11.

{

"value": "Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef (\"ovl: stack file ops\"). This was fixed in kernel version 5.8 by commits 56230d9 (\"ovl: verify permissions in ovl_path_open()\"), 48bd024 (\"ovl: switch to mounter creds in readdir\") and 05acefb (\"ovl: check permission to open real file\"). Additionally, commits 130fdbc (\"ovl: pass correct flags for opening real directory\") and 292f902 (\"ovl: call secutiry hook in ovl_real_ioctl()\") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da (\"ovl: do not fail because of O_NOATIMEi\") in kernel 5.11."

CVE-2020-10781 (GCVE-0-2020-10781)
Vulnerability from nvd – Published: 2020-09-16 00:00 – Updated: 2024-08-04 11:14

Summary
A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.

Summary
A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.

Summary
A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality.

Summary
A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per task/process conditional STIPB switching was added on top of the existing SSBD switching. The highest threat from this vulnerability is to confidentiality.

Summary
A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability.

Arbitrary Memory read in BPF Linux Kernel
Summary
There exists an arbitrary memory read within the Linux Kernel BPF - Constants provided to fill pointers in structs passed in to bpf_sys_bpf are not verified and can point anywhere, including memory not owned by BPF. An attacker with CAP_BPF can arbitrarily read memory from anywhere on the system. We recommend upgrading past commit 86f44fcec22c

Title
Linux Kernel LoadPin bypass via dm-verity table reload
Summary
Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5

Title
Linux Kernel sctp_destroy_sock race condition
Summary
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
Severity
6.7 (Medium)
CWE
- CWE-362 - Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization)

Title
Unprivileged overlay + shiftfs read access
Summary
Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef ("ovl: stack file ops"). This was fixed in kernel version 5.8 by commits 56230d9 ("ovl: verify permissions in ovl_path_open()"), 48bd024 ("ovl: switch to mounter creds in readdir") and 05acefb ("ovl: check permission to open real file"). Additionally, commits 130fdbc ("ovl: pass correct flags for opening real directory") and 292f902 ("ovl: call secutiry hook in ovl_real_ioctl()") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da ("ovl: do not fail because of O_NOATIMEi") in kernel 5.11.

CVE-2020-10781 (GCVE-0-2020-10781)
Vulnerability from cvelistv5 – Published: 2020-09-16 00:00 – Updated: 2024-08-04 11:14
VLAI

VEX
Summary
A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.

Summary
A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.

Summary
A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality.

Summary
A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per task/process conditional STIPB switching was added on top of the existing SSBD switching. The highest threat from this vulnerability is to confidentiality.

Summary
A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability.
