CVE-2026-90323: CVE-2026-90323: güvenlik açığı
Açıklama (NVD)
In the Linux kernel, the following vulnerability has been resolved: ublk: validate auto buf reg before taking uring_cmd With UBLK_F_AUTO_BUF_REG, invalid sqe->addr can fail after ublk_fill_io_cmd() has set UBLK_IO_FLAG_ACTIVE. The uring_cmd is completed while the tag stays active, which can hang teardown. Split validation from buffer apply so the check has no side effects, then take the uring_cmd and store the already-validated buffer. Apply the same order in FETCH so io->buf is not written before __ublk_fetch() state checks.
