Memory corruption via oversized camera buffer metadata
Published Jul 6, 2026 · Updated Jul 6, 2026
Out-of-bounds write in Qualcomm Snapdragon camera drivers allows local users with low privileges to corrupt memory via malformed camera input. The validation path accepts an input batch size and buffer-plane count above their permitted maxima, enabling writes beyond the intended buffer. Exploitation requires local access and high-complexity conditions without user interaction; no reliable crash, code-execution, or privilege-escalation outcome is published.
