CVE-2026-72316

A flaw was found in the Linux kernel's device mapper dm era target. When the metadataopen function fails to allocate memory, it returns a NULL pointer. The calling function, eractr, does not correctly validate this return, leading to a NULL pointer dereference when the metadata is accessed. This...
