CVE-2026-31504

A flaw was found in the Linux kernel. A race condition in the packetrelease function, specifically during a network device up NETDEVUP event, can lead to a Use-After-Free UAF vulnerability. This occurs when a socket is re-registered into a fanout group's array, leaving a dangling pointer. A local...

CVE-2026-31469

A flaw was found in the Linux kernel's virtionet driver. A local user can trigger a Use-After-Free UAF vulnerability by configuring the driver with specific network settings and then destroying the network namespace while data packets are still being transmitted. This premature freeing of network...
