CVE-2026-53018

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the f2fs file system where the kernel may incorrectly initiate I/O to read pages that have already been updated during Garbage Collection (GC). This occurs when a page is moved between block addresses; for instance, if a page is moved from block address A to B and marked as uptodate, a subsequent move from B to C may trigger a kernel BUG via VM BUG ON FOLIO during the endio process initiated by ra data block(). The failure happens because the system attempts to read the page from the previous block address despite it already being current.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
