In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in sameclienthaslease sameclienthaslease returns an opinfo pointer from ci-moplist after dropping ci-mlock without taking a reference. smbgrantoplock then dereferences that pointer in copylease and when...

EUVD-2026-59259

In the Linux kernel, the following vulnerability has been resolved: drm/xe/pf: Don't attempt to process FASTREQ or EVENT relays Currently defined VF/PF relay actions use regular REQUEST messages only and the PF shouldn't attempt to handle FASTREQUEST nor EVENT messages as this would result in...

CVE-2026-72360 drm/xe/pf: Don't attempt to process FAST_REQ or EVENT relays

In the Linux kernel, the following vulnerability has been resolved: drm/xe/pf: Don't attempt to process FASTREQ or EVENT relays Currently defined VF/PF relay actions use regular REQUEST messages only and the PF shouldn't attempt to handle FASTREQUEST nor EVENT messages as this would result in...

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...
