Impact
A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem. This flaw allows a local user to cause an out-of-bounds write issue.
Patches
The fix has been backported to 5.15.32 version of the upstream Linux kernel (5.15 is the upstream Kernel long term version Talos ships with). Talos >= v1.0.0 is shipped with Linux Kernel 5.15.32+ fixing the above issue.
Workarounds
It's recommended to upgrade, the exploit is not trivial to reproduce.
