Local memory corruption via HGSL IOCTL use-after-free
Published Nov 4, 2024 · Updated Nov 4, 2024
Use-after-free in Qualcomm Snapdragon HGSL memory handling allows local users to corrupt memory through crafted IOCTL calls. The HGSL memory-node IOCTL path dereferences an object after its lifetime ends, although Qualcomm has not disclosed the responsible function or lifetime transition. Exploitation requires low-privileged local access to the HGSL interface and can corrupt memory in the affected execution context.
