https://notcve.org/view.php?id=CVE-2024-41016
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. • https://git.kernel.org/stable/c/57a3d89831fcaa2cdbe024b47c7c36d5a56c3637 https://git.kernel.org/stable/c/c031d286eceb82f72f8623b7f4abd2aa491bfb5e https://git.kernel.org/stable/c/cfb926051fab19b10d1e65976211f364aa820180 https://git.kernel.org/stable/c/c726dea9d0c806d64c26fcef483b1fb9474d8c5e https://git.kernel.org/stable/c/e4ffea01adf3323c821b6f37e9577d2d400adbaa https://git.kernel.org/stable/c/af77c4fc1871847b528d58b7fdafb4aa1f6a9262 •

https://notcve.org/view.php?id=CVE-2024-41014
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 ensure that tail_blk and head_blk are the same, which will result in the inability to enter xlog_recover_process_data 3) Write a tool to parse and modify the copied image in step 2 4) Make the end of the xlog_op_header entries only 1 byte away from xlog_rec_header->h_size 5) xlog_rec_header->h_num_logops++ 6) Modify xlog_rec_header->h_crc Fix: Add a check to make sure there is sufficient space to access fixed members of xlog_op_header. • https://git.kernel.org/stable/c/fb63435b7c7dc112b1ae1baea5486e0a6e27b196 https://access.redhat.com/security/cve/CVE-2024-41014 https://bugzilla.redhat.com/show_bug.cgi?id=2300297 • CWE-125: Out-of-bounds Read •
CVSS: 7.1EPSS: 0%CPEs: 1EXPL: 0CVE-2024-41013 – xfs: don't walk off the end of a directory data block
https://notcve.org/view.php?id=CVE-2024-41013
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 space will be considered as dup or dep. We may encounter an out of bound read when accessing the fixed members. In the patch, we make sure that the remaining bytes large enough to hold an unused entry before accessing xfs_dir2_data_unused and xfs_dir2_data_unused is XFS_DIR2_DATA_ALIGN byte aligned. • https://git.kernel.org/stable/c/0c7fcdb6d06cdf8b19b57c17605215b06afa864a https://access.redhat.com/security/cve/CVE-2024-41013 https://bugzilla.redhat.com/show_bug.cgi?id=2300296 • CWE-125: Out-of-bounds Read •
