CVE-2026-46023

A flaw was found in the Linux kernel's device mapper dm mirror component. A local user could exploit an integer overflow vulnerability in the createdirtylog function by providing a specially crafted device mapper table string. This could lead to out-of-bounds reads, potentially causing system...

CVE-2026-46023

In the Linux kernel, the following vulnerability has been resolved: dm mirror: fix integer overflow in createdirtylog The argument count calculation in createdirtylog performs argsused = 2 + paramcount before validating against argc. When a user provides a paramcount close to UINTMAX via the devi...

CVE-2026-46023

CVE-2026-46023 is a Linux kernel vulnerability in dm-mirror where create_dirty_log() could bypass argc checks due to an unsigned add of 2 + param_count, allowing an out-of-bounds read in argv when param_count is near UINT_MAX. The root cause is an overflow in argument count calculation before val...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm mpath: Added the missing dmputdevice call when failing to obtain the scsi dh name. When commit fd81bc5cca8f “scsi: devicehandler: Returning an error pointer in scsidhattachedhandlername”, code was added to fail the parsing of...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm: A crash occurs if blkallocdisk fails. If blkallocdisk fails, the variable md-disk is set to an error value. cleanupmappeddevice will notice that md-disk is non-NULL and will attempt to access it, resulting in a crash at the...

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...
