CVE-2024-38571

Kernel crash via TSENS calibration null dereference

Published Jun 19, 2024 · Updated May 11, 2026

NULL pointer dereference in the TSENS thermal driver allows local users to crash affected Linux kernels during sensor calibration. The compute_intercept_slope() debug log dereferences p2[i] even though calibrate_8960() passes p2 as NULL for one-point calibration. Reachability requires the Qualcomm 8960 TSENS calibration path and DEBUG or DYNAMIC_DEBUG; exploitation causes an availability-only kernel crash.
