CVE-2025-40145 PCI/pwrctrl: Fix double cleanup on devm_add_action_or_reset() failure

In the Linux kernel, the following vulnerability has been resolved: PCI/pwrctrl: Fix double cleanup on devmaddactionorreset failure When devmaddactionorreset fails, it calls the passed cleanup function. Hence the caller must not repeat that cleanup. Replace the "goto errregulatorfree" by the actu...

In the Linux kernel, the following vulnerability has been resolved: igb: Fix potential invalid memory access in igbinitmodule The pciregisterdriver can fail and when this happened, the dcanotifier needs to be unregistered, otherwise the dcanotifier can be called when igb fails to install, resulti...

CVE-2025-58149

A flaw was found in Xen. When passing through PCI devices, the detach logic in libxl won't remove access permissions to any 64bit memory BARs the device might have. As a result a domain can still have access to any 64bit memory BAR when such device is no longer assigned to the domain. A buggy or...

USN-7864-1: Linux kernel (GCP and GKE) vulnerabilities

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...

CVE-2025-58149 Incorrect removal of permissions on PCI device unplug

When passing through PCI devices, the detach logic in libxl won't remove access permissions to any 64bit memory BARs the device might have. As a result a domain can still have access any 64bit memory BAR when such device is no longer assigned to the domain. For PV domains the permission leak allo...
