CVE-2026-89639

This vulnerability affects the Linux kernel's CIFS (Common Internet File System) implementation. When a file is opened with O_TRUNC , the function cifs_do_truncate() is invoked without holding i_rwsem, preventing it from performing a proper fscache cookie resize . As a result, stale cached data c...
