Overview
Affected versions of this package are vulnerable to Expired Pointer Dereference via the k_pipe_init syscall in CONFIG_USERSPACE builds. An attacker can corrupt kernel wait queues and scheduler structures by re-initializing an in-use k_pipe object, leading to invalid kernel writes, lost wakeups, indefinitely blocked threads, and silent data loss.
