  - In the Linux kernel, the following vulnerability has been resolved: ext4: avoid allocating blocks from     corrupted group in ext4_mb_find_by_goal() Places the logic for checking if the group's block bitmap is     corrupt under the protection of the group lock to avoid allocating blocks from the group with a corrupted     block bitmap. (CVE-2024-26772)

  - In the Linux kernel, the following vulnerability has been resolved: ext4: fix corruption during on-line     resize We observed a corruption during on-line resize of a file system that is larger than 16 TiB with 4k     block size. With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue     can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode. An on-     line resize across an 8 GiB boundary (the size of a meta block group in this setup) then leads to a     corruption: dev=/dev/<some_dev> # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O     ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096     of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test #     79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page     cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test #     3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test 2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the     number of blocks per block group and 2^6 are the number of block groups that make a meta block group. The     last checksum might be different depending on how the file is laid out across the physical blocks. The     actual corruption occurs at physical block 63*2^15 = 2064384 which would be the location of the backup of     the meta block group's block descriptor. During the on-line resize the file system will be converted to     meta_bg starting at s_first_meta_bg which is 2 in the example - meaning all block groups after 16 GiB.
    However, in ext4_flex_group_add we might add block groups that are not part of the first meta block group     yet. In the reproducer we achieved this by substracting the size of a whole block group from the point     where the meta block group would start. This must be considered when updating the backup block group     descriptors to follow the non-meta_bg layout. The fix is to add a test whether the group to add is already     part of the meta block group or not. (CVE-2024-35807)

  - In the Linux kernel, the following vulnerability has been resolved: block: fix overflow in     blk_ioctl_discard() There is no check for overflow of 'start + len' in blk_ioctl_discard(). Hung task     occurs if submit an discard ioctl with the following param: start = 0x80000000000ff000, len =     0x8000000000fff000; Add the overflow validation now. (CVE-2024-36917)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
