CVE-2026-53303

Description

A flaw was found in the Linux kernel's f2fs filesystem. This vulnerability allows for potential out-of-bounds memory access or the display of stale data. It occurs because the extension_list and related counts are read without proper synchronization, enabling a concurrent system file system (sysfs) store operation to modify the list while it is being accessed. This inconsistency can lead to system instability or incorrect information being presented.
