In the Linux kernel, the following vulnerability has been resolved: mm: list_lru: fix UAF for memory cgroup The mem_cgroup_from_slab_obj() is supposed to be called under rcu lock or cgroup_mutex or others which could prevent returned memcg from being freed. Fix it by adding missing rcu read lock. Found by code inspection. [songmuchun@bytedance.com: only grab rcu lock when necessary, per Vlastimil]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: list_lru: corrige UAF para memoria cgroup Se supone que mem_cgroup_from_slab_obj() debe llamarse bajo rcu lock o cgroup_mutex u otros, lo que podría impedir que se libere el memcg devuelto. Solucionarlo agregando el bloqueo de lectura rcu que falta. Encontrado mediante inspección de código. [songmuchun@bytedance.com: solo tome el bloqueo rcu cuando sea necesario, según Vlastimil] Enlace: https://lkml.kernel.org/r/20240801024603.1865-1-songmuchun@bytedance.com
