CVE-2023-53489

CVE-2023-53489 affects the Linux kernel memory handling for UDP sockets with TX timestamps and zerocopy skbs. The issue is a memory leak: clones of skbs and their ubuf references can keep a socket refcnt and skb references in the error/clock path, causing leaked sk, sock and skb when close() is c...

CVE-2021-47449

A vulnerability was found in the Linux kernel vulnerability that affects the ice driver, specifically related to the locking mechanism for the Transmission Tx timestamp tracking flush. The issue arose after the addition of a lock around the Tx timestamp tracker flow, which handles cleanup of...
