CVE-2026-64425

CVE-2026-64425 affects the Linux kernel's io_uring/io-wq subsystem. A prior fix introduced a check for IO_WQ_BIT_EXIT in the outer work run loop, but it still snapshots the exit bit once before processing an entire dependent linked-work chain. If io_wq_exit_start() sets the bit after the first li...

CVE-2026-43366 io_uring/kbuf: check if target buffer list is still legacy on recycle

In the Linux kernel, the following vulnerability has been resolved: iouring/kbuf: check if target buffer list is still legacy on recycle There's a gap between when the buffer was grabbed and when it potentially gets recycled, where if the list is empty, someone could've upgraded it to a ring...

Linux kernel io-uring Heap Buffer Overflow DoS

The vulnerability of the createioworker function in the iouring/io-wq.c module, a component of the Linux kernel’s asynchronous input/output interface, is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to cause service failures...

SUSE CVE-2026-23113

In the Linux kernel, the following vulnerability has been resolved: iouring/io-wq: check IOWQBITEXIT inside work run loop Currently this is checked before running the pending work. Normally this is quite fine, as work items either end up blocking which will create a new worker for other items, or...

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...

CVE-2026-23113

CVE-2026-23113 affects the Linux kernel io-uring/io-wq component. The issue stems from not checking IO_WQ_BIT_EXIT in the io_worker_handle_work() loop, causing long exits when processing large pending reads (e.g., 2GB reads from /dev/msr* with >16MB per read). Evidence in the advisory shows th...
