WID-SEC-W-2024-0645
Vulnerability from csaf_certbund - Published: 2024-03-14 23:00 - Updated: 2024-05-07 22:00Es gibt eine Schwachstelle in libvirt aufgrund einer NULL-Zeiger-Dereferenz in der Funktion "udevConnectListAllInterfaces()". Dies kann ausgelöst werden, wenn eine Host-Schnittstelle getrennt wird, während die Liste der Schnittstellen mit der "virConnectListAllInterfaces"-API erzeugt wird. Ein lokaler Angreifer kann dies ausnutzen, um einen Denial-of-Service auszulösen.
