In __pkvm_host_share_guest of mem_protect.c, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in Android's __pkvm_host_share_guest function allows unprivileged attackers to achieve kernel-level code execution through integer overflow-induced out-of-bounds memory writes. The vulnerability requires no user interaction and can be exploited directly from any local context on affected devices. A patch is available to address this high-severity flaw.
Technical ContextAI
Classified as CWE-190 (Integer Overflow or Wraparound). Affects Android. In __pkvm_host_share_guest of mem_protect.c, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
