  3. CVE-2024-38663
In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix list corruption from resetting io stat Since commit 3b8cc6298724 ("blk-cgroup: Optimize blkcg_rstat_flush()"), each iostat instance is added to blkcg percpu list, so blkcg_reset_stats() can't reset the stat instance by memset(), otherwise the llist may be corrupted. Fix the issue by only resetting the counter part.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: blk-cgroup: corrige la corrupción de la lista al restablecer io stat Desde el commit 3b8cc6298724 ("blk-cgroup: Optimizar blkcg_rstat_flush()"), cada instancia de iostat se agrega a la lista de percpu de blkcg, por lo que blkcg_reset_stats() no puede restablecer la instancia de estadísticas mediante memset(); de lo contrario, la lista puede estar dañada. Solucione el problema reiniciando solo la contraparte.
