CVE-2021-1905 is a use-after-free vulnerability in Qualcomm graphics/GPU components affecting multiple Snapdragon product lines, including Snapdragon Auto, Compute, Connectivity, Consumer IoT, Industrial IoT, Mobile, Voice & Music, and Wearables. The flaw is caused by improper handling of memory mapping when multiple processes interact with the GPU subsystem simultaneously. Under these conditions, stale memory may be referenced after it has been freed, creating a memory safety condition in the graphics driver path. The issue was noted as potentially having been exploited in limited, targeted attacks prior to patch availability.
