CVE-2026-74709

A flaw was found in the Linux kernel's xsk AFXDP sockets component. A local attacker, by manipulating metadata flags after request processing, could cause the kernel to write a timestamp into the metadata area even when not explicitly requested. This could lead to unintended data modification...

CVE-2026-74707

A flaw was found in the Linux kernel's xsk AFXDP sockets component. This vulnerability allows a local user to bypass security validation by modifying transmission TX metadata after it has been initially checked but before it is used to prepare hardware requests. This could lead to unexpected syst...
