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...

CVE-2026-43314

CVE-2026-43314 affects the Linux kernel device mapper (dm) driver. The issue arises when an I/O timeout failure is injected into a dm device; because dm does not implement its own timeout handler, the request can leak and hang indefinitely. The root cause is the presence of blk_should_fake_timeou...

CVE-2026-43309 md raid: fix hang when stopping arrays with metadata through dm-raid

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...

Linux Distros Unpatched Vulnerability : CVE-2026-43309

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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 ha...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the dm driver’s failure to implement timeout handling and its reliance on slave devices. When an...

CVE-2026-43278

A flaw was found in the Linux kernel's device-mapper dm component, specifically affecting request-based device-mapper targets like dm-multipath. Stale bio pointers in cloned requests can lead to double-initialization and subsequent double-free scenarios of cloned bios. This memory corruption...

CVE-2026-43192

A flaw was found in the Linux kernel's device-mapper multipath dm mpath subsystem. A missing cleanup operation occurs when the system fails to retrieve a SCSI device handler name due to memory allocation issues. This oversight can lead to a resource leak, where references to path devices are not...

EUVD-2026-27674

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...

EUVD-2026-27752

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...

EUVD-2026-27692

In the Linux kernel, the following vulnerability has been resolved: dm-verity: correctly handle dmbufioclientcreate failure If either of the calls to dmbufioclientcreate in verityfecctr fails, then dmbufioclientdestroy is later called with an ERRPTR argument. That causes a crash. Fix this...
