CVE-2026-23412

A flaw was found in the Linux kernel's netfilter BPF Berkeley Packet Filter component. A local attacker could exploit this by initiating a concurrent process to dump hooks via nfnetlinkhooks, which triggers a use-after-free vulnerability. This could lead to system instability or a denial of servi...
