NVD Description

Note: Versions mentioned in the description apply only to the upstream ocfs2-kmp-default package and not the ocfs2-kmp-default package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAP_SYS_ADMIN capability.
