CVE ID :CVE-2026-53126<\/p>\n
Published : June 24, 2026, 4:30 p.m. | 1\u00a0hour, 13\u00a0minutes ago<\/p>\n
Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
blk-cgroup: fix disk reference leak in blkcg_maybe_throttle_current()<\/p>\n
Add the missing put_disk() on the error path in
\nblkcg_maybe_throttle_current(). When blkcg lookup, blkg lookup, or
\nblkg_tryget() fails, the function jumps to the out label which only
\ncalls rcu_read_unlock() but does not release the disk reference acquired
\nby blkcg_schedule_throttle() via get_device(). Since current->throttle_disk
\nis already set to NULL before the lookup, blkcg_exit() cannot release
\nthis reference either, causing the disk to never be freed.<\/p>\n
Restore the reference release that was present as blk_put_queue() in the
\noriginal code but was inadvertently dropped during the conversion from
\nrequest_queue to gendisk.<\/p>\n
Severity: 0.0 | NA<\/p>\n
