Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

fuse: limit FUSENOTIFYRETRIEVE to uptodate folios

FUSENOTIFYRETRIEVE must be limited to uptodate folios; !uptodate folios can contain uninitialized data. Since FUSENOTIFYRETRIEVE is intended to only return data that is already in the page cache and not wait for data from the FUSE daemon, treat !uptodate folios as if they weren't present.

This only has security impact on systems that don't enable automatic zero-initialization of all page allocations via CONFIGINITONALLOCDEFAULTON or initon_alloc=1.(CVE-2026-53167)
