- Summary
- blk-cgroup: Fix class @block_class's subsystem refcount leakage
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: Fix class @block_class's subsystem refcount leakage
blkcgfillrootiostats() iterates over @blockclass's devices by classdeviter(init|next)(), but does not end iterating with classdeviterexit(), so causes the class's subsystem refcount leakage.
Fix by ending the iterating with classdeviter_exit().
