CVE-2026-53033

A flaw was found in the Linux kernel's sockmap functionality. A race condition exists in the unix_stream_bpf_update_proto() function when a BPF (Berkeley Packet Filter) iterator program updates a sockmap. This can lead to a use-after-free (UaF) vulnerability, where memory is accessed after it has been freed. An attacker could potentially exploit this to cause a denial of service or achieve arbitrary code execution.
