CWE-400  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 5.11.11 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.
