CVE-2026-52981

CVE-2026-52981 concerns a Linux kernel issue in neigh_xmit: when called with an uninitialized neighbor table (e.g., NEIGH_ND_TABLE with IPv6 disabled), neigh_xmit can return -EAFNOSUPPORT without releasing the skb, risking a memory leak. The fix removes the remaining code path that could neither ...
