CVE-2025-68222

Dependent-driver disruption via uninitialized descriptor fields

Published Dec 16, 2025 · Updated Dec 16, 2025

Use of uninitialized memory in the Linux kernel 6.4 and later allows attackers to disrupt dependent-driver probing via unspecified vectors. The S32CC pin-control probe allocates s32_pinctrl_desc without clearing every field, then passes an indeterminate num_custom_params value into device-tree configuration parsing. Reachability requires the S32CC driver and associated NXP hardware; no attacker-controlled trigger is disclosed, and the documented consequence is intermittent allocation and parse failure in dependent drivers.
