NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-4_12_14-25_3-default package and not the kernel-livepatch-4_12_14-25_3-default package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free).
