Linux Distros Unpatched Vulnerability : CVE-2025-40023

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: drm/xe/vf: Don't expose sysfs attributes not applicable for VFs VFs can't read...

CVE-2025-40023

CVE-2025-40023 concerns a Linux kernel issue in the drm/xe/vf path where sysfs attributes that are not applicable to Virtual Functions (VFs) are exposed. The description notes that VFs cannot read the BMG_PCIE_CAP(0x138340) register nor access PCODE (guarded by info.skip_pcode), and attempting to...

CVE-2025-40023: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vf: Don't expose sysfs attributes not applicable for VFs VFs can't read BMGPCIECAP0x138340 register nor access PCODE already guarded by the info.skippcode flag so we shouldn't expose attributes that require any of them to...
