Service interruption via wrong pin descriptor check
Published Aug 28, 2026 · Updated Aug 28, 2026
NULL pointer dereference in Linux 6.13 allows attackers to interrupt affected SpacemiT systems via unspecified vectors. spacemit_pin_set_config checks the numeric pin identifier instead of the descriptor returned by spacemit_get_pin, then dereferences a NULL descriptor; the same check also rejects valid pin zero and skips its PAD configuration. Reachability requires the SpacemiT pin-control driver and a pin absent from the SoC table, while the published record does not establish attacker control or the exact interruption mode.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
