Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Google Android ausnutzen, um seine Privilegien zu erhöhen, vertrauliche Informationen offenzulegen, beliebigen Code auszuführen und einen Denial-of-Service-Zustand auszulösen.
WID-SEC-W-2022-0138Linux Kernel: Schwachstelle ermöglicht PrivilegieneskalationDeutsch2022-01-13csaf · cert_bundDE
Ein lokaler Angreifer kann eine Schwachstelle im Linux Kernel ausnutzen, um seine Privilegien zu erhöhen.
PUB-A-2158142622022-06-01vendor · osvUS
In kernel/bpf/verifier.c , there is a possible way to manipulate pointer arithmetic due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
