CVE-2022-4139 – kernel: i915: Incorrect GPU TLB flush can lead to random memory access
https://notcve.org/view.php?id=CVE-2022-4139
12 Jan 2023 — An incorrect TLB flush issue was found in the Linux kernel’s GPU i915 kernel driver, potentially leading to random memory corruption or data leaks. This flaw could allow a local user to crash the system or escalate their privileges on the system. The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts are installed using a special build of Red Hat Enterprise Linux... • https://bugzilla.redhat.com/show_bug.cgi?id=2147572 • CWE-281: Improper Preservation of Permissions CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2022-4696 – Debian Security Advisory 5324-1
https://notcve.org/view.php?id=CVE-2022-4696
11 Jan 2023 — There exists a use-after-free vulnerability in the Linux kernel through io_uring and the IORING_OP_SPLICE operation. If IORING_OP_SPLICE is missing the IO_WQ_WORK_FILES flag, which signals that the operation won't use current->nsproxy, so its reference counter is not increased. This assumption is not always true as calling io_splice on specific files will call the get_uts function which will use current->nsproxy leading to invalidly decreasing its reference counter later causing the use-after-free vulnerabi... • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=75454b4bbfc7e6a4dd8338556f36ea9107ddf61a • CWE-416: Use After Free CWE-763: Release of Invalid Pointer or Reference •

CVE-2022-2196 – Speculative execution attacks in KVM VMX
https://notcve.org/view.php?id=CVE-2022-2196
09 Jan 2023 — 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 A flaw was found in the KVM's Intel nested virtualization feature (nVMX).

09 Jan 2023 — A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges. It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges.

CVE-2022-4378 – kernel: stack overflow in do_proc_dointvec and proc_skip_spaces
https://notcve.org/view.php?id=CVE-2022-4378
05 Jan 2023 — A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.
