- net/ulp: use-after-free in listening ULP sockets (CVE-2023-0461)
- cpu: AMD CPUs may transiently execute beyond unconditional direct branch (CVE-2021-26341)
- malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory (CVE-2021-33655)
- possible race condition in drivers/tty/tty_buffers.c (CVE-2022-1462)
- KVM: NULL pointer dereference in kvm_mmu_invpcid_gva (CVE-2022-1789)
- use-after-free in free_pipe_info() could lead to privilege escalation (CVE-2022-1882)
- KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks (CVE-2022-2196)
- netfilter: nf_conntrack_irc message handling issue (CVE-2022-2663)
- race condition in xfrm_probe_algs can lead to OOB read/write (CVE-2022-3028)

Title
Speculative execution attacks in KVM VMX
Summary
A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past commit 2e7eab81425a

EPSS
Summary
An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.
Severity ?
No CVSS data available.

Summary
In the linux kernel, if IMA appraisal is used with the "ima_appraise=log" boot param, lockdown can be defeated with kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents setting "ima_appraise=log" from the boot param when Secure Boot is enabled, but this does not cover cases where lockdown is used without Secure Boot. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity, Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

Summary
An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.

Title
Use-after-free vulnerability in the Linux Kernel
Summary
There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.
There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.
When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable.
The setsockopt TCP_ULP operation does not require any privilege.
We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c

Title
Info Leak in l2cap_core in the Linux Kernel
Summary
There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively) remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within proximity of the victim.
We recommend upgrading past commit https://www.google.com/url https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4 https://www.google.com/url

Summary
In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c.

Summary
A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.
