# Qualcomm Multiple Chipsets: 4 exploited vulnerabilities · pwn.watch

> Multiple Qualcomm chipsets contain a use-after-free vulnerability when process shell memory is freed using IOCTL munmap call and process initialization is in progress. Multiple Qualcomm chipsets contain a use-after-free vulnerability due to memory corruption in DSP Services during a remote call from HLOS to DSP. Multiple Qualcomm chipsets contain a use of out-of-range pointer offset vulnerability due to memory corruption in Graphics while submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND. Multiple Qualcomm chipsets contain an integer overflow vulnerability due to memory corruption in Graphics Linux while assigning shared virtual memory region during IOCTL call.
