# Memory corruption while submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND

Multiple Qualcomm chipsets have a memory corruption bug in the Graphics driver when a large list of sync points is submitted through the KGSL IOCTL_KGSL_GPU_AUX_COMMAND call. Per the CISA KEV listing, it is exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._

## Fix

Apply the vendor's security bulletin patch for the affected Qualcomm chipset; CISA says to apply vendor remediations or discontinue use if none exist.

## From the sources

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.

CISA required action: Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.
