kernel: net/sched: act_ct: Only release RCU read lock after ct_ft

A flaw was found in the Linux kernel. A race condition in the actct module, specifically during the flow table lookup, can lead to a Use-After-Free UAF vulnerability. This occurs because a critical lock is released prematurely, allowing a memory object to be freed while still in use. An attacker...

kernel: ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get
