CVE-2026-68386

The CVE concerns the Linux kernel’s BPF sockmap path. It describes a vulnerability where unhashed UDP sockets accepted by sockmap can have their refcount incremented via a BPF lookup, and if the socket becomes bound, the subsequent bpf_sk_release() may skip decreasing the refcount, leading to a m...
