Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ublk: The SQE128 flag is validated before accessing the cmd field. The ublkctrlcmddump function accesses the sqe-cmd field before checking the IOURINGFSQE128 flag. This could lead to out-of-boundary memory access. The flag...

In the Linux kernel, the following vulnerability has been resolved: UBLK: Failure to recover a device if queue setup is interrupted. In ublkctrlendrecovery, if waitforcompletioninterruptible is interrupted by a signal, the queues are not set up successfully. Therefore, we must fail the...

CVE-2026-74472

A flaw was found in the Linux kernel's ublk driver. This vulnerability arises from improper initialization of kernel-owned device information fields when a new ublk device is added. A local attacker could exploit this by providing malformed device information, which may lead to a kernel panic,...
