CVE-2026-23113

A flaw was found in the Linux kernel's iouring subsystem. When io-wq worker threads process extremely long-running I/O operations such as large reads from /dev/msr devices, the exit path may be delayed for an extended period because the IOWQBITEXIT flag is only checked before the work loop begins...
