CVE-2026-64426

A file reference leak in the Linux kernel's io_uring/nop component occurs when a NOP request is submitted with IOSQE_FIXED_FILE set but without IORING_NOP_FIXED_FILE . The io_nop() handler takes the normal file-acquisition path and grabs a real file reference via io_file_get_normal() , but on com...

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...
