CVE-2022-1016: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.

Affected products

• Linux Linux Kernel: up to and including 3.12; from 3.13, up to and including 5.17; version 3.13 only
• Red Hat Enterprise Linux: version 8.0 only; version 9.0 only
