CVE-2023-23586 – Use after free in io_uring in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-23586
17 Feb 2023 — Due to a vulnerability in the io_uring subsystem, it is possible to leak kernel memory information to the user process. timens_install calls current_is_single_threaded to determine if the current process is single-threaded, but this call does not consider io_uring's io_worker threads, thus it is possible to insert a time namespace's vvar page to process's memory space via a page fault. When this time namespace is destroyed, the vvar page is also freed, but not removed from the process' memory, and a next pa... • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/io_uring?h=linux-5.10.y&id=788d0824269bef539fe31a785b1517882eafed93 • CWE-416: Use After Free •
CVE-2022-3424
https://notcve.org/view.php?id=CVE-2022-3424
10 Feb 2023 — A use-after-free flaw was found in the Linux kernel’s SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://bugzilla.redhat.com/show_bug.cgi?id=2132640 • CWE-416: Use After Free •
CVE-2023-0590 – kernel: use-after-free due to race condition in qdisc_graft()
https://notcve.org/view.php?id=CVE-2023-0590
10 Feb 2023 — A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 ("net: sched: fix race condition in qdisc_graft()") not applied yet, then kernel could be affected. • https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html • CWE-416: Use After Free •
CVE-2023-0615
https://notcve.org/view.php?id=CVE-2023-0615
06 Feb 2023 — A memory leak flaw and potential divide by zero and Integer overflow was found in the Linux kernel V4L2 and vivid test code functionality. This issue occurs when a user triggers ioctls, such as VIDIOC_S_DV_TIMINGS ioctl. This could allow a local user to crash the system if vivid test code enabled. • https://bugzilla.redhat.com/show_bug.cgi?id=2166287 • CWE-20: Improper Input Validation CWE-190: Integer Overflow or Wraparound CWE-369: Divide By Zero CWE-401: Missing Release of Memory after Effective Lifetime •

CVE-2023-0240 – Use after free in io_uring in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-0240
30 Jan 2023 — There is a logic error in io_uring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the last io_grab_identity call cannot return false is not true, and in this case the function will use the init_cred or the previous linked requests identity to do operations instead of using the current identity. This can lead to reference counting issues causing use-after-free. We recommend upgrading past ve... • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/io_uring?h=linux-5.10.y&id=788d0824269bef539fe31a785b1517882eafed93 • CWE-416: Use After Free •
