CVE-2022-33233

Local memory corruption via protected-file write command

Published Feb 9, 2023 · Updated Aug 3, 2024

Memory corruption in Qualcomm Snapdragon modem firmware allows local users to corrupt memory by targeting write-protected files. The modem command path accepts a protected-file write under a weak configuration and corrupts memory instead of rejecting the operation. Reachability requires local low-privileged access; Qualcomm has not disclosed the command interface, corrupted object, or resulting control flow.
