queue corruption

Queue corruption in the Linux kernel can occur when internal socket queues become inconsistent due to locking bugs. A notable example is CVE-2026-23066, a flaw in the RxRPC recvpath where incorrect requeue logic in rxrpc_recvmsg() corrupts socket queues, leading to use-after-free and refcount underruns. This vulnerability was introduced by a subtle locking issue and was fixed upstream with a targeted kernel patch in early 2026. On WindowsForum.com, discussions about queue corruption often focus on kernel-level bugs, their impact on system stability, and the importance of applying security patches to prevent exploitation.
