  3. CVE-2023-52940
In the Linux kernel, the following vulnerability has been resolved: mm: multi-gen LRU: fix crash during cgroup migration lru_gen_migrate_mm() assumes lru_gen_add_mm() runs prior to itself. This isn't true for the following scenario: CPU 1 CPU 2 clone() cgroup_can_fork() cgroup_procs_write() cgroup_post_fork() task_lock() lru_gen_migrate_mm() task_unlock() task_lock() lru_gen_add_mm() task_unlock() And when the above happens, kernel crashes because of linked list corruption (mm_struct->lru_gen.list).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: LRU multigeneración: se corrige un fallo durante la migración de cgroup. lru_gen_migrate_mm() asume que lru_gen_add_mm() se ejecuta antes que él mismo. Esto no se cumple en el siguiente escenario: CPU 1 CPU 2 clone() cgroup_can_fork() cgroup_procs_write() cgroup_post_fork() task_lock() lru_gen_migrate_mm() task_unlock() task_lock() lru_gen_add_mm() task_unlock(). Cuando esto ocurre, el kernel se bloquea debido a la corrupción de la lista enlazada (mm_struct->lru_gen.list).
