Kernel memory corruption via stale persist-buffer object
Published Oct 7, 2024 · Updated Oct 7, 2024
Use after free in Qualcomm Snapdragon ComputerVision allows local users to corrupt kernel memory through a crafted persist-buffer IOCTL request. A freed object remains reachable while the user-space ComputerVision path sends the persist-buffer command packet to kernel space. High-privileged local access is required; successful exploitation can disclose, alter, or corrupt kernel memory and interrupt the device.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
