- Summary
- md/bitmap: resume array on backlog_store() error path
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
md/bitmap: resume array on backlog_store() error path
backlog_store() suspends the array before checking whether a write-mostly device exists. If no such device exists, the error path only unlocks reconfig_mutex and leaves the array suspended, blocking subsequent I/O.
Use mddev_unlock_and_resume() to release both states.
