Lifecycle Timeline
2Description
In pcie, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10315038 / ALPS10340155; Issue ID: MSV-5155.
Analysis
Local privilege escalation in Android's PCIe driver allows system-level attackers to execute arbitrary code through an out-of-bounds write caused by insufficient bounds validation. Exploitation requires pre-existing system privileges but no user interaction, enabling a compromised system component to gain complete device control. …
