CVE-2022-25665

Kernel memory disclosure via buffer over-read

Published Oct 12, 2022 · Updated May 15, 2025

Out-of-bounds read in the kernel of Qualcomm Snapdragon platforms allows local users to disclose memory through a buffer over-read. The closed-source kernel component reads beyond the intended buffer boundary, but Qualcomm has not disclosed the affected function, input, or exact length-validation error. Local execution on a device containing an affected chipset is required; the bounded consequences are kernel-memory disclosure and limited service interruption, with no integrity impact.
