Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

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.(CVE-2021-33909)
