Red Hat Security Advisory: kernel-rt security and bug fix update

Severity

Important

Scope

3 vulnerabilities in this advisory, including CVE-2022-25636.

CVE-2022-25636

An out-of-bounds (OOB) memory access flaw was found in nft_fwd_dup_netdev_offload in net/netfilter/nf_dup_netdev.c in the netfilter subcomponent in the Linux kernel due to a heap out-of-bounds write problem. This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat.
