USN-6576-1

Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle an expired catchall element in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
