Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ublk: The kernel-owned devinfo fields are reset in the ublkctrladddev function. The memcpy function copies the ublksrvctrldevinfo from the user space into ub-devinfo, and then updates the fields owned by the driver. However, i...

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...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ublk: Fix for deadlock when reading the partition table When a process such as udev opens the ublk block device e.g., to read the partition table using bdevopen, a deadlock can occur: 1. bdevopen grabs the disk-openmutex. 2. The...

CVE-2026-90323

A flaw was found in the Linux kernel's ublk subsystem. When the automatic buffer registration feature is active, an invalid buffer address can be processed, causing a command to complete while its associated tag remains active. This can lead to a system hang during resource teardown, allowing a...

CVE-2026-90324

A flaw was found in the ublk component of the Linux kernel. A local attacker, by providing an invalid address range from a userspace ublk server, could cause the importubuf function to fail. This failure, if not properly handled, leads to an uninitialized data structure being used in subsequent...

CVE-2026-90181

A flaw was found in the Linux kernel's ublk universal block driver. A local attacker could trigger an xarray allocation failure during the teardown of a shared memory zero-copy SHMEMZC buffer. This issue causes the teardown process to enter an infinite retry loop, preventing forward progress and...

SUSE CVE-2026-89793

In the Linux kernel, the following vulnerability has been resolved: ublk: clear VMMAYWRITE on read-only ublk char device mmap ublkchmmap rejects mmap requests with VMWRITE set, but never clears VMMAYWRITE on the resulting read-only mapping. This allows a userspace daemon to mmap the per-queue...

SUSE CVE-2026-90181
