MEDIUM

Linux Kernel 6.2-6.6.32, 6.7-6.9.3, 6.10 - List Corruption via blkcg_reset_stats()

Title source: llm

Description

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.
