ARM pKVM Memory Protection Flaws

Local privilege escalation in Android's mem_protect.c results from integer overflow conditions that enable out-of-bounds memory writes, allowing unauthenticated local attackers to gain elevated system privileges without user interaction. The vulnerability affects multiple functions within the memory protection component and is exploitable by any process on the affected device. A patch is available to address this high-severity issue.

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.

Local privilege escalation in Android's pKVM hypervisor initialization allows unprivileged attackers to corrupt memory and gain elevated privileges without user interaction. The vulnerability stems from a logic error in the __pkvm_init_vm function that fails to properly validate memory operations during VM setup. A patch is available to address this high-severity flaw affecting Android devices.

Local privilege escalation in Android's mem_protect.c allows unprivileged attackers to achieve full system access through an out-of-bounds write caused by insufficient bounds validation. The vulnerability requires no user interaction and can be exploited immediately upon device compromise by any local process.

Android versions up to - contains a vulnerability that allows attackers to local escalation of privilege with no additional execution privileges needed (CVSS 8.4).

A logic error in Android's mem_protect.c enables local attackers to write out-of-bounds memory and escalate privileges without requiring additional permissions or user interaction. This vulnerability affects Android devices and can be exploited by any local user to gain elevated system privileges. A patch is available.
