Descriptions
In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix list corruption from reorder of WRITE ->lqueued __blkcg_rstat_flush() can be run anytime, especially when blk_cgroup_bio_start
is being executed. If WRITE of `->lqueued` is re-ordered with READ of 'bisc->lnode.next' in
the loop of __blkcg_rstat_flush(), `next_bisc` can be assigned with one
stat instance being added in blk_cgroup_bio_start(), then the local
list in __blkcg_rstat_flush() could be corrupted. Fix the issue by adding one barrier.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: blk-cgroup: corrupción de la lista de arreglos debido al reordenamiento de WRITE ->lqueued __blkcg_rstat_flush() se puede ejecutar en cualquier momento, especialmente cuando se está ejecutando blk_cgroup_bio_start. Si la ESCRITURA de `->lqueued` se reordena con la READ de 'bisc->lnode.next' en el bucle de __blkcg_rstat_flush(), se puede asignar `next_bisc` agregando una instancia de estadística en blk_cgroup_bio_start(), entonces el La lista local en __blkcg_rstat_flush() podría estar dañada. Solucione el problema agregando una barrera.
