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...
