About this tag
The multishot receive tag on WindowsForum.com covers discussions about the CVE-2026-23473 vulnerability in Linux's io_uring subsystem, where a multishot receive operation can hang indefinitely due to a wakeup race that misses a terminal EOF or HUP condition. The bug occurs when a send and shutdown happen back-to-back, causing the poll loop to drain references without rechecking for persistent shutdown state. This results in a socket operation that hangs rather than crashing. The content focuses on kernel reliability and networking path issues, relevant to Linux system administrators and developers dealing with io_uring performance and stability.
