CVE-2024-23376

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.
