NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-4_12_14-150_75-default package and not the kernel-livepatch-4_12_14-150_75-default package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05.
