USN-7291-1: Linux kernel vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - x86 architecture; - Block layer subsystem; - ACPI drivers; - GPU drivers; - HID subsystem; -...

USN-7293-1 linux, linux-hwe-5.4 vulnerabilities

Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service system crash or possibly execute arbitrary code...

DEBIAN-CVE-2022-49341

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Clear prog-jitedlen along prog-jited syzbot reported an illegal copytouser attempt from bpfproggetinfobyfd 1 There was no repro yet on this bug, but I think that commit 0aef499f3172 "mm/usercopy: Detect vmalloc...

UBUNTU-CVE-2022-49721

In the Linux kernel, the following vulnerability has been resolved: arm64: ftrace: consistently handle PLTs. Sometimes it is necessary to use a PLT entry to call an ftrace trampoline. This is handled by ftracemakecall and ftracemakenop, with each having almost identical logic, but this is not...

CVE-2022-49721

CVE-2022-49721 affects the Linux kernel (arm64) ftrace. The root cause is inconsistent handling of PLT entries when calling ftrace trampolines: ftrace_modify_call() can produce out-of-range branches, causing warnings and no code change, or replace the old branch with a BRK, risking a kernel panic...

CVE-2022-49520 arm64: compat: Do not treat syscall number as ESR_ELx for a bad syscall

In the Linux kernel, the following vulnerability has been resolved: arm64: compat: Do not treat syscall number as ESRELx for a bad syscall If a compat process tries to execute an unknown system call above the ARMNRCOMPATEND number, the kernel sends a SIGILL signal to the offending process...

CVE-2022-49520

CVE-2022-49520 (Linux kernel, arm64 compat): The vulnerability occurs when a compat process executes an unknown syscall above __ARM_NR_COMPAT_END; the kernel incorrectly uses the syscall number as ESR_ELx for the fault, causing arm64_show_signal() to print bogus ESR messages. The fix is to stop u...

CVE-2022-49426 iommu/arm-smmu-v3-sva: Fix mm use-after-free

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3-sva: Fix mm use-after-free We currently call arm64mmcontextput without holding a reference to the mm, which can result in use-after-free. Call mmgrab/mmdrop to ensure the mm only gets freed after we unpinned the...

CVE-2022-49341

The CVE-2022-49341 entry concerns the Linux kernel vulnerability where bpf, arm64 paths could reveal kernel memory via copy_to_user() in bpf_prog_get_info_by_fd() due to incorrect handling of prog->jited_len. The issue arises when prog->jited_len is set (e.g., to 43) but prog->bpf_func i...
