CVE-2026-89985

CVE-2026-89985 is a vulnerability in the Linux kernel's memory cgroup (memcg) subsystem . The root cause is a broken invariant in memcg_reparent_objcgs(): when a folio migrates across NUMA nodes, it inherits the old node's objcg, which desynchronizes objcg reparenting from LRU list reparenting. T...

CVE-2026-89985 memcg: keep folio's objcg same as its node

In the Linux kernel, the following vulnerability has been resolved: memcg: keep folio's objcg same as its node memcgreparentobjcgs has an inherent assumption that a folio's objcg is the objcg of the folio's node. Folio migration across nodes breaks that assumption: the new folio simply inherits t...
