Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A denial-of-service issue was detected, possibly due to a recursive locking scenario, which led to a deadlock in the tableclear function in drivers/md/dm-ioctl.c within the Linux Kernel Device Mapper-Multipathing sub-component...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: dm integrity: Memory corruption occurs when tagsize is less than digestsize. It is possible to configure dm-integrity in such a way that the tagsize parameter is smaller than the actual digestsize. In this case, a portion of the...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: dm rq: Fixed a double-free of blkmqtagset when removing a device after table loading fails. When loading a device-mapper table for a request-based mapped device, and the allocation/initialization of the blkmqtagset for the device...

In the Linux kernel, the following vulnerabilities have been resolved: - dm clone: Fixed a UAF Use-after-Free in clonedtr. - Dmclone also has the same UAF issue when dmresume and dmdestroy are executed concurrently. Therefore, the timer is canceled again in clonedtr...

kernel: dm: fix NULL pointer dereference in __dm_suspend()

In the Linux kernel, the following vulnerability has been resolved: dm: fix NULL pointer dereference in dmsuspend There is a race condition between dm device suspend and table load that can lead to null pointer dereference. The issue occurs when suspend is invoked before table load completes: BUG...

kernel: Linux kernel: Denial of Service via deadlock in block layer sysfs store callbacks

A flaw was found in the Linux kernel. A local user could exploit a vulnerability where freezing the request queue within certain sysfs store callbacks can lead to a deadlock. This issue may occur when combined with the device-mapper multipath dm-multipath driver and the queueifnopath option, or...

SUSE CVE-2026-43309

In the Linux kernel, the following vulnerability has been resolved: md raid: fix hang when stopping arrays with metadata through dm-raid When using device-mapper's dm-raid target, stopping a RAID array can cause the system to hang under specific conditions. This occurs when: - A dm-raid managed...

SUSE CVE-2026-43192

In the Linux kernel, the following vulnerability has been resolved: dm mpath: Add missing dmputdevice when failing to get scsi dh name When commit fd81bc5cca8f "scsi: devicehandler: Return error pointer in scsidhattachedhandlername" added code to fail parsing the path if scsidhattachedhandlername...

SUSE CVE-2026-43278

In the Linux kernel, the following vulnerability has been resolved: dm: clear cloned request bio pointer when last clone bio completes Stale rq-bio values have been observed to cause double-initialization of cloned bios in request-based device-mapper targets, leading to use-after-free and...

CVE-2026-43314

A flaw was found in the Linux kernel's device mapper dm driver. When an I/O timeout failure is intentionally introduced to a device mapper device, the driver does not correctly manage the timeout. This oversight causes a request to remain uncompleted, leading to system tasks hanging indefinitely...

CVE-2026-43309

A flaw was found in the Linux kernel's md raid and device-mapper dm-raid components. When a local user or system operation attempts to stop a RAID array managed by dm-raid, the system can experience an indefinite hang. This occurs because the mdstop function tries to write to metadata sub-devices...
