high Tenable Self-Hosted Container Security Plugin ID 466560

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: Squashfs: sanity check symbolic link
size Syzkiller reports a "KMSAN: uninit-value in pick_link" bug. This is caused by an uninitialised page,
which is ultimately caused by a corrupted symbolic link size read from disk. The reason why the corrupted
symlink size causes an uninitialised page is due to the following sequence of events: 1.
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value
3875536935 to inode->i_size. 2. Later squashfs_symlink_read_folio() is called, which assigns this
corrupted value to the length variable, which being a signed int, overflows producing a negative number.
3. The following loop that fills in the page contents checks that the copied bytes is less than length,
which being negative means the loop is skipped, producing an uninitialised page. This patch adds a sanity
check which checks that the symbolic link size is not larger than expected. -- V2: fix spelling mistake.
(CVE-2024-46744)
