In the Linux kernel, the following vulnerability has been resolved: s390/pci: Fix potential double remove of hotplug slot In commit 6ee600bfbe0f "s390/pci: remove hotplug slot when releasing the device" the zpciexitslot was moved from zpcidevicereserved to zpcireleasedevice with the intention of...

CVE-2024-56699

In CVE-2024-56699, the Linux kernel on s390 PCI (zPCI) could double-remove a hotplug slot due to zpci_exit_slot() being moved to zpci_release_device() and released only after all refs dropped. The non-reserved path tear-down incorrectly affected both configured and standby states, risking hotplug...
