- Summary
- CVE-2026-53168 affecting package kernel for versions less than 6.6.143.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
fuse: reject fuse_notify() pagecache ops on directories
The operations FUSENOTIFYSTORE and FUSENOTIFYRETRIEVE allow the FUSE daemon to actively write/read pagecache contents.
For directories with FOPENCACHEDIR, the pagecache is used as kernel-internal cache storage, and userspace is not supposed to have direct access to this cache - in particular, fuseparsecache() will hit WARN_ON() if the cache contains bogus data.
Reject FUSENOTIFYSTORE and FUSENOTIFYRETRIEVE on anything other than regular files with -EINVAL.
