CVE-2025-37757
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
tipc: fix memory leak in tipc_link_xmit
In case the backlog transmit queue for system-importance messages is overloaded, tipc_link_xmit() returns -ENOBUFS but the skb list is not purged. This leads to memory leak and failure when a skb is allocated.
This commit fixes this issue by purging the skb list before tipc_link_xmit() returns.
