Local information disclosure via hypervisor-log processing
Published Oct 9, 2025 · Updated Oct 9, 2025
Improper input validation in Qualcomm Snapdragon TZ firmware allows local users to read confidential data during hypervisor-log processing. Qualcomm has not published the affected function, the untrusted log field, or the validation operation that fails during processing. Exploitation requires local low-privileged access and crosses a security boundary, with no reported integrity or availability impact.
