CVE-2026-52981

A flaw was found in the Linux kernel. The neighxmit function, when called with an uninitialized neighbor table such as NEIGHNDTABLE when IPv6 is disabled, can return an error without properly releasing the allocated skb socket buffer. This can lead to a memory leak, potentially impacting system...

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 ...
