29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix signedness bug in sdma_v4_0_process_trap_irq() The "instance" variable needs to be signed for the error handling to work. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of ser... • https://git.kernel.org/stable/c/5594971e02764aa1c8210ffb838cb4e7897716e8 •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: filelock: Fix fcntl/close race recovery compat path When I wrote commit 3cad1bc01041 ("filelock: Remove locks reliably when fcntl/close race is detected"), I missed that there are two copies of the code I was patching: The normal version, and the version for 64-bit offsets on 32-bit kernels. Thanks to Greg KH for stumbling over this while doing the stable backport... Apply exactly the same fix to the compat path for 32-bit kernels.

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate ff offset This adds sanity checks for ff offset. There is a check on rt->first_free at first, but walking through by ff without any check. If the second ff is a large offset. We may encounter an out-of-bound read.

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() xattr in ocfs2 maybe 'non-indexed', which saved with additional space requested. It's better to check if the memory is out of bound before memcmp, although this possibility mainly comes from crafted poisonous images.

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: xfs: add bounds checking to xlog_recover_process_data There is a lack of verification of the space occupied by fixed members of xlog_op_header in the xlog_recover_process_data. We can create a crafted image to trigger an out of bounds read by following these steps: 1) Mount an image of xfs, and do some file operations to leave records 2) Before umounting, copy the image for subsequent steps to simulate abnormal exit. Because umount will ens... • https://git.kernel.org/stable/c/d1e3efe783365db59da88f08a2e0bfe1cc95b143 • CWE-125: Out-of-bounds Read •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: xfs: don't walk off the end of a directory data block This adds sanity checks for xfs_dir2_data_unused and xfs_dir2_data_entry to make sure don't stray beyond valid memory region. Before patching, the loop simply checks that the start offset of the dup and dep is within the range. So in a crafted image, if last entry is xfs_dir2_data_unused, we can change dup->length to dup->length-1 and leave 1 byte of space. In the next traversal, this sp... • https://git.kernel.org/stable/c/ca96d83c93071f95cf962ce92406621a472df31b • CWE-125: Out-of-bounds Read •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: tun: add missing verification for short frame The cited commit missed to check against the validity of the frame length in the tun_xdp_one() path, which could cause a corrupted skb to be sent downstack. Even before the skb is transmitted, the tun_xdp_one-->eth_type_trans() may access the Ethernet header although it can be less than ETH_HLEN. Once transmitted, this could either cause out-of-bound access beyond the actual length, or confuse t... • https://git.kernel.org/stable/c/043d222f93ab8c76b56a3b315cd8692e35affb6c • CWE-20: Improper Input Validation •
