Memory corruption via invalid camera port index
Published Jul 6, 2026 · Updated Jul 6, 2026
Out-of-bounds write in the Qualcomm Snapdragon camera driver allows local users to corrupt memory through malformed port indices. When updating prepared commands, the driver accepts a user-space port index beyond the supported read-client limit and writes outside the intended bounds. Exploitation requires local low-privilege access and a high-complexity trigger; the corruption crosses a security boundary and affects data and service availability.
