CVE-2024-38384

CVE-2024-38384 (Linux kernel) - The blk-cgroup subsystem had a race where reordering WRITE to the lqueued field with a READ of bisc->lnode.next inside __blkcg_rstat_flush() could corrupt a local list. The issue could occur anytime __blkcg_rstat_flush() runs, especially during blk_cgroup_bio_st...

CVE-2024-38663 blk-cgroup: fix list corruption from resetting io stat

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 blkcgrstatflush", each iostat instance is added to blkcg percpu list, so blkcgresetstats can't reset the stat instance by...

CVE-2024-38663

CVE-2024-38663 (Linux kernel) affects the blk-cgroup iostat/stat reset path. After commit 3b8cc6298724, each iostat instance is added to the blkcg per-CPU list, so blkcg_reset_stats() can’t reset the stat instance by memset(), risking list corruption. The fix is to reset only the counter portion,...
