CVE-2026-72360

The CVE-2026-72360 entry concerns the Linux kernel, specifically the DRM XE PCIe PF path. The vulnerability arises from PF relay logic attempting to process FAST_REQ or EVENT relays; VF/PF relay actions were defined only for regular REQUEST messages. This misbehavior could break the VFPF ABI prot...
