CVE-2023-1249 – kernel: missing mmap_lock in file_files_note that could possibly lead to a use after free in the coredump code
https://notcve.org/view.php?id=CVE-2023-1249
21 Mar 2023 — A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected. The kernel tree of CentOS Stream 9 suffers from multiple use-after-free conditions that were already patched in upstream stable trees. • https://packetstorm.news/files/id/171912 • CWE-416: Use After Free •
CVE-2022-48423 – Ubuntu Security Notice USN-6079-1
https://notcve.org/view.php?id=CVE-2022-48423
19 Mar 2023 — In the Linux kernel before 6.1.3, fs/ntfs3/record.c does not validate resident attribute names. An out-of-bounds write may occur. It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.3 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-48425
19 Mar 2023 — In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs. Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel contained a race condition during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Hyunwoo Kim discovered that the Technotrend/Hauppauge USB DEC driver in the Linux kernel did not proper... • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=467333af2f7b95eeaa61a5b5369a80063cd971fd • CWE-763: Release of Invalid Pointer or Reference •

https://notcve.org/view.php?id=CVE-2023-0030
08 Mar 2023 — A use-after-free flaw was found in the Linux kernel’s nouveau driver in how a user triggers a memory overflow that causes the nvkm_vma_tail function to fail. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://bugzilla.redhat.com/show_bug.cgi?id=2157270 • CWE-416: Use After Free •
CVE-2022-3707 – kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed
https://notcve.org/view.php?id=CVE-2022-3707
03 Mar 2023 — A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could allow a local user to crash the system. 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. • https://bugzilla.redhat.com/show_bug.cgi?id=2137979 • CWE-415: Double Free CWE-460: Improper Cleanup on Thrown Exception •
CVE-2023-1118 – kernel: use-after-free in drivers/media/rc/ene_ir.c due to race condition

02 Mar 2023 — A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. A use-after-free flaw was found in the Linux kernel's integrated infrared receiver/transceiver driver. This issue occurs when a user detaches a rc device.

01 Mar 2023 — In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached. • https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2 • CWE-476: NULL Pointer Dereference •
