high Tenable Self-Hosted Container Security Plugin ID 458700

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: ocfs2: fix listxattr handling when the
 buffer is full [BUG] If an OCFS2 inode has both inline and block-based xattrs, listxattr() can return a
 size larger than the caller's buffer when the inline names consume that buffer exactly. kernel BUG at

 ("ocfs2: Refactor xattr list and remove ocfs2_xattr_handler().") replaced the old per-handler list
 accounting with ocfs2_xattr_list_entry(), but it kept using size == 0 to detect probe mode. That
 assumption stops being true once ocfs2_listxattr() finishes the inline-xattr pass. If the inline names
 fill the caller buffer exactly, the block-xattr pass runs with a non-NULL buffer and a remaining size of
 zero. ocfs2_xattr_list_entry() then skips the bounds check, keeps counting block names, and returns a
 positive size larger than the supplied buffer. [FIX] Detect probe mode by testing whether the destination
 buffer pointer is NULL instead of whether the remaining size is zero. That restores the pre-refactor
 behavior and matches the OCFS2 getxattr helpers. Once the remaining buffer reaches zero while more names
 are left, the block-xattr pass now returns -ERANGE instead of reporting a size larger than the allocated
 list buffer. (CVE-2026-53041)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
