CVE-2026-72138

A flaw was found in the xen/gntdev component of the Linux kernel. When the gntdevioctlmapgrantref function fails to copy operation results back to userspace, it does not properly release a memory reference. This oversight can lead to a memory leak and a corrupted list entry. A local attacker coul...
