Description

A vulnerability was found in the Linux kernel's Unix domain socket (af_unix) implementation, where stale Out-of-Band (OOB) data is not cleared from the receive queue. This issue arises when OOB data is dequeued but the associated oob_skb is not cleared, leading to incorrect behavior in subsequent recv() calls. It can cause deadlocks, improper data handling, and incorrect socket polling.
