CVE-2026-53167

MEDIUM

7.0

CVSS v3

NVD

Description

In the Linux kernel, the following vulnerability has been resolved: fuse: limit FUSE_NOTIFY_RETRIEVE to uptodate folios FUSE_NOTIFY_RETRIEVE must be limited to uptodate folios; !uptodate folios can contain uninitialized data. Since FUSE_NOTIFY_RETRIEVE 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 CONFIG_INIT_ON_ALLOC_DEFAULT_ON or init_on_alloc=1.
