CVE-2026-72491

A flaw was found in the Linux kernel's net/9p RDMA transport module. An inconsistent locking mechanism around the rdma-state field allows for a race condition during connection teardown. This can lead to lost state transitions, corrupting the connection state machine. Consequently, a use-after-fr...

CVE-2026-72166

A flaw was found in the Linux kernel's 9p client remote procedure call RPC implementation. When the p9clientrpc function is called with a P9TFLUSH request and the transport has no peer, a fatal signal can cause an infinite loop. This prevents the affected process from terminating, leading to a...
