Kernel memory corruption via QSEECOM type race
Published Feb 7, 2020 · Updated Aug 5, 2024
A QSEECOM race condition in Qualcomm Snapdragon chipsets allows local users with device access to corrupt kernel memory. Concurrent QSEECOM ioctls can change the shared handle's type while __qseecom_update_cmd_buf processes it, mixing listener and client handling without consistent bounds assumptions. Exploitation requires access to /dev/qseecom; the demonstrated outcome is a kernel panic, while controlled memory corruption enables kernel privilege escalation.
