NVD Description

Note: Versions mentioned in the description apply only to the upstream realtime-kernel package and not the realtime-kernel package as distributed by RHEL.

In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact.
