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

Description Crafted EROFS images containing valid volume labels can trigger incorrect early returns in volume label handling, leading to folio reference leaks. Folio reference leaks occur when the system fails to properly release memory references for folios (memory management units that group pages), potentially consuming system resources over time. This issue does not cause system crashes or other severe impacts.

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