In the Linux kernel, the following vulnerability has been resolved: jfs: don't walk off the end of ealist Add a check before visiting the members of ea to make sure each ea stays within the ealist. • https://git.kernel.org/stable/c/7f91bd0f2941fa36449ce1a15faaa64f840d9746 https://git.kernel.org/stable/c/fc16776a82e8df97b6c4f9a10ba95aa44cef7ba5 https://git.kernel.org/stable/c/6386f1b6a10e5d1ddd03db4ff6dfc55d488852ce https://git.kernel.org/stable/c/7e21574195a45fc193555fa40e99fed16565ff7e https://git.kernel.org/stable/c/4e034f7e563ab723b93a59980e4a1bb33198ece8 https://git.kernel.org/stable/c/17440dbc66ab98b410514b04987f61deedb86751 https://git.kernel.org/stable/c/f4435f476b9bf059cd9e26a69f5b29c768d00375 https://git.kernel.org/stable/c/dbde7bc91093fa9c2410e418b236b70fd •

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/af77c4fc1871847b528d58b7fdafb4aa1f6a9262 •

CVSS: 6.1EPSS: 0%CPEs: 1EXPL: 0CVE-2024-41014 – xfs: add bounds checking to xlog_recover_process_data
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: -EPSS: 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 •
