"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nublk: validate auto buf reg before taking uring_cmd\n\nWith UBLK_F_AUTO_BUF_REG, invalid sqe->addr can fail after\nublk_fill_io_cmd() has set UBLK_IO_FLAG_ACTIVE. The uring_cmd is\ncompleted while the tag stays active, which can hang teardown.\n\nSplit validation from buffer apply so the check has no side effects,\nthen take the uring_cmd and store the already-validated buffer. Apply\nthe same order in FETCH so io->buf is not written before __ublk_fetch()\nstate checks."
