medium Tenable Self-Hosted Container Security Plugin ID 451912

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: ext4: dax: fix overflowing extents
beyond inode size when partially writing The dax_iomap_rw() does two things in each iteration: map written
blocks and copy user data to blocks. If the process is killed by user(See signal handling in
dax_iomap_iter()), the copied data will be returned and added on inode size, which means that the length
of written extents may exceed the inode size, then fsck will fail. An example is given as: dd
if=/dev/urandom of=file bs=4M count=1 dax_iomap_rw iomap_iter // round 1 ext4_iomap_begin ext4_iomap_alloc
// allocate 0~2M extents(written flag) dax_iomap_iter // copy 2M data iomap_iter // round 2
iomap_iter_advance iter->pos += iter->processed // iter->pos = 2M ext4_iomap_begin ext4_iomap_alloc //
allocate 2~4M extents(written flag) dax_iomap_iter fatal_signal_pending done = iter->pos - iocb->ki_pos //
done = 2M ext4_handle_inode_extension ext4_update_inode_size // inode size = 2M fsck reports: Inode 13,
i_size is 2097152, should be 4194304. Fix? Fix the problem by truncating extents if the written length is
smaller than expected. (CVE-2024-50015)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.236.26 or later.
