Memory corruption via undersized RNG output buffer
Published Jun 1, 2026 · Updated Jun 1, 2026
Out-of-bounds write in Qualcomm Snapdragon RNG command handling allows local users with high privileges to corrupt memory. The command handler accepts an output buffer smaller than the random-number-generator result and writes beyond that buffer. Successful access requires local execution with high privileges and can compromise confidentiality, integrity, and availability within the affected component.
