WID-SEC-W-2022-0232
Vulnerability from csaf_certbund - Published: 2021-12-26 23:00 - Updated: 2023-08-13 22:00Im Linux Kernel existieren mehrere Schwachstellen. Die Fehler bestehen, weil die Hash-Tabelle sehr klein ist und weil bei der Verwendung einer Hash-Tabelle nicht berücksichtigt wird, dass IPv6-basierte Angreifer in der Regel unter vielen IPv6-Quelladressen wählen können. Ein lokaler Angreifer kann diese Schwachstellen ausnutzen, um vertrauliche Informationen offenzulegen.
