kernel: net: bridge: use a stable FDB dst snapshot in RCU readers

A flaw was found in the Linux kernel. Inconsistent handling of local Forwarding Database FDB entries in the bridge networking component's RCU Read-Copy-Update readers can lead to a null-pointer dereference. A local attacker could exploit this by triggering a concurrent update to an FDB entry,...

kernel: procfs: fix missing RCU protection when reading real_parent in do_task_stat()

A flaw was found in the Linux kernel's procfs component. When reading /proc/pid/stat, the dotaskstat function accesses task-realparent without proper Read-Copy-Update RCU protection. This missing protection creates a race condition, which can lead to a Use-After-Free UAF vulnerability. A local...
