CVE-2026-80729

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

Description An issue exists where xas try split() adds GFP ACCOUNT for page-cache xa nodes, but folio split() fails to set the xa lru of the xa state. This allows a live, memcg-charged xa node to exist without being linked into the mapping's shadow nodes list lru. Consequently, when the reclaim process later traverses the list lru, it triggers a VM WARN ON(!css is dying()) warning.

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