Astra Linux – vulnerability in linux-6.12, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: iouring/io-wq: check IOWQBITEXIT inside work run loop Currently this check is performed before executing pending work items. Normally this works fine, as work items either block triggering creation of a new worker for subsequent...

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...
