  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: airoha: Fix potential use-after-free in airoha_ppe_deinit()  airoha_ppe_deinit() replaces the NPU pointer with NULL via rcu_replace_pointer() but does not wait for existing RCU readers to exit before calling ppe_deinit() and airoha_npu_put(). This can cause a use-after-free if a reader in an RCU read-side critical section still holds a reference to the NPU when it is freed.  The init path (airoha_ppe_init) already calls synchronize_rcu() after rcu_assign_pointer(), but the deinit path introduced in commit 6abcf751bc08 (\u0022net: airoha: Fix schedule while atomic in airoha_ppe_deinit()\u0022) omitted the matching barrier when switching from rcu_read_lock()/rcu_dereference() to rcu_replace_pointer().  Add synchronize_rcu() before ppe_deinit() to ensure all existing RCU readers have completed before the NPU resources are released.",
