CVE-2026-45975

CVE-2026-45975 is a Linux kernel vulnerability in the ublk subsystem where a race condition can occur reading struct ublksrv_ctrl_cmd from userspace-mapped memory in the io_uring_sqe. The fix uses READ_ONCE() to copy ublksrv_ctrl_cmd from the io_uring_sqe to a local stack copy and then operates o...
