Vulnerability from variot - Updated: 2025-12-22 21:46

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. The security impact is negligible as CAP_SYS_ADMIN inherently gives the ability to deny service.

CVE-2022-1016

David Bouman discovered a flaw in the netfilter subsystem where the
nft_do_chain function did not initialize register data that
nf_tables expressions can read from and write to. A local user with access to
/dev/kvm could cause the MMU emulator to update page table entry
flags at the wrong address.

CVE-2022-1195

Lin Ma discovered race conditions in the 6pack and mkiss hamradio
drivers, which could lead to a use-after-free.

CVE-2022-1198

Duoming Zhou discovered a race condition in the 6pack hamradio
driver, which could lead to a use-after-free.

CVE-2022-1199, CVE-2022-1204, CVE-2022-1205

Duoming Zhou discovered race conditions in the AX.25 hamradio
protocol, which could lead to a use-after-free or null pointer
dereference.

CVE-2022-1353

The TCS Robot tool found an information leak in the PF_KEY
subsystem.

CVE-2022-1516

A NULL pointer dereference flaw in the implementation of the X.25
set of standardized network protocols, which can result in denial
of service.

This driver is not enabled in Debian's official kernel
configurations.

This driver is not enabled in Debian's official kernel

linux-azure-5.13, linux-oracle-5.13 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description: - linux-azure-5.13: Linux kernel for Microsoft Azure cloud systems - linux-oracle-5.13: Linux kernel for Oracle Cloud systems

Details:

It was discovered that the BPF verifier in the Linux kernel did not properly restrict pointer types in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-23222)

It was discovered that the network traffic control implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1055)

Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. (CVE-2022-0492)

J\xfcrgen Gro\xdf discovered that the Xen subsystem within the Linux kernel did not adequately limit the number of events driver domains (unprivileged PV backends) could send to other guest VMs. An attacker in a driver domain could use this to cause a denial of service in other guest VMs. (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

J\xfcrgen Gro\xdf discovered that the Xen network backend driver in the Linux kernel did not adequately limit the amount of queued packets when a guest did not process them. An attacker in a guest VM can use this to cause a denial of service (excessive kernel memory consumption) in the network backend domain. (CVE-2021-28714, CVE-2021-28715)

Szymon Heidrich discovered that the USB Gadget subsystem in the Linux kernel did not properly restrict the size of control requests for certain gadget types, leading to possible out of bounds reads or writes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-39685)

It was discovered that a race condition existed in the poll implementation in the Linux kernel, resulting in a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-39698)

It was discovered that the simulated networking device driver for the Linux kernel did not properly initialize memory in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-4135)

Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. (CVE-2021-4197)

Brendan Dolan-Gavitt discovered that the aQuantia AQtion Ethernet device driver in the Linux kernel did not properly validate meta-data coming from the device. A local attacker who can control an emulated device can use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-43975)

It was discovered that the ARM Trusted Execution Environment (TEE) subsystem in the Linux kernel contained a race condition leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-44733)

It was discovered that the Phone Network protocol (PhoNet) implementation in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45095)

It was discovered that the eBPF verifier in the Linux kernel did not properly perform bounds checking on mov32 operations. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2021-45402)

It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45480)

It was discovered that the BPF subsystem in the Linux kernel did not properly track pointer types on atomic fetch operations in some situations. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2022-0264)

It was discovered that the TIPC Protocol implementation in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0382)

Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435)

It was discovered that the KVM implementation for s390 systems in the Linux kernel did not properly prevent memory operations on PVM guests that were in non-protected mode. A local attacker could use this to obtain unauthorized memory write access. (CVE-2022-0516)

It was discovered that the ICMPv6 implementation in the Linux kernel did not properly deallocate memory in certain situations. A remote attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2022-0742)

It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-27666)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04 LTS: linux-image-5.13.0-1021-azure 5.13.0-1021.24~20.04.1 linux-image-5.13.0-1025-oracle 5.13.0-1025.30~20.04.1 linux-image-azure 5.13.0.1021.24~20.04.10 linux-image-oracle 5.13.0.1025.30~20.04.1

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.

A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2022-23222)\n\nIt was discovered that the network traffic control implementation in the\nLinux kernel contained a use-after-free vulnerability. A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2022-1055)\n\nYiqi Sun and Kevin Wang discovered that the cgroups implementation in the\nLinux kernel did not properly restrict access to the cgroups v1\nrelease_agent feature. (CVE-2022-0492)\n\nJ\\xfcrgen Gro\\xdf discovered that the Xen subsystem within the Linux kernel did\nnot adequately limit the number of events driver domains (unprivileged PV\nbackends) could send to other guest VMs. An attacker in a driver domain\ncould use this to cause a denial of service in other guest VMs. \n(CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)\n\nJ\\xfcrgen Gro\\xdf discovered that the Xen network backend driver in the Linux\nkernel did not adequately limit the amount of queued packets when a guest\ndid not process them. An attacker in a guest VM can use this to cause a\ndenial of service (excessive kernel memory consumption) in the network\nbackend domain. (CVE-2021-28714, CVE-2021-28715)\n\nSzymon Heidrich discovered that the USB Gadget subsystem in the Linux\nkernel did not properly restrict the size of control requests for certain\ngadget types, leading to possible out of bounds reads or writes. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2021-39685)\n\nIt was discovered that a race condition existed in the poll implementation\nin the Linux kernel, resulting in a use-after-free vulnerability. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2021-39698)\n\nIt was discovered that the simulated networking device driver for the Linux\nkernel did not properly initialize memory in certain situations. A local\nattacker could use this to expose sensitive information (kernel memory). \n(CVE-2021-4135)\n\nEric Biederman discovered that the cgroup process migration implementation\nin the Linux kernel did not perform permission checks correctly in some\nsituations. (CVE-2021-4197)\n\nBrendan Dolan-Gavitt discovered that the aQuantia AQtion Ethernet device\ndriver in the Linux kernel did not properly validate meta-data coming from\nthe device. A local attacker who can control an emulated device can use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2021-43975)\n\nIt was discovered that the ARM Trusted Execution Environment (TEE)\nsubsystem in the Linux kernel contained a race condition leading to a use-\nafter-free vulnerability. A local attacker could use this to cause a denial\nof service or possibly execute arbitrary code. (CVE-2021-44733)\n\nIt was discovered that the Phone Network protocol (PhoNet) implementation\nin the Linux kernel did not properly perform reference counting in some\nerror conditions. A local attacker could possibly use this to cause a\ndenial of service (memory exhaustion). (CVE-2021-45095)\n\nIt was discovered that the eBPF verifier in the Linux kernel did not\nproperly perform bounds checking on mov32 operations. A local attacker\ncould use this to expose sensitive information (kernel pointer addresses). \n(CVE-2021-45402)\n\nIt was discovered that the Reliable Datagram Sockets (RDS) protocol\nimplementation in the Linux kernel did not properly deallocate memory in\nsome error conditions. A local attacker could possibly use this to cause a\ndenial of service (memory exhaustion). (CVE-2021-45480)\n\nIt was discovered that the BPF subsystem in the Linux kernel did not\nproperly track pointer types on atomic fetch operations in some situations. \nA local attacker could use this to expose sensitive information (kernel\npointer addresses). (CVE-2022-0264)\n\nIt was discovered that the TIPC Protocol implementation in the Linux kernel\ndid not properly initialize memory in some situations. A local attacker\ncould use this to expose sensitive information (kernel memory). \n(CVE-2022-0382)\n\nSamuel Page discovered that the Transparent Inter-Process Communication\n(TIPC) protocol implementation in the Linux kernel contained a stack-based\nbuffer overflow. A remote attacker could use this to cause a denial of\nservice (system crash) for systems that have a TIPC bearer configured. \n(CVE-2022-0435)\n\nIt was discovered that the KVM implementation for s390 systems in the Linux\nkernel did not properly prevent memory operations on PVM guests that were\nin non-protected mode. A local attacker could use this to obtain\nunauthorized memory write access. (CVE-2022-0516)\n\nIt was discovered that the ICMPv6 implementation in the Linux kernel did\nnot properly deallocate memory in certain situations. A remote attacker\ncould possibly use this to cause a denial of service (memory exhaustion). \n(CVE-2022-0742)\n\nIt was discovered that the IPsec implementation in the Linux kernel did not\nproperly allocate enough memory when performing ESP transformations,\nleading to a heap-based buffer overflow. A local attacker could use this to\ncause a denial of service (system crash) or possibly execute arbitrary\ncode.
