CVE-2026-80650

Use-after-free via probe error fallthrough

Published Aug 28, 2026 · Updated Aug 28, 2026

Use-after-free in the Linux kernel gc2235 camera driver allows attackers to trigger invalid memory access during a failed device probe. When media_entity_pads_init() fails, gc2235_probe() frees the device through gc2235_remove() but still calls atomisp_register_i2c_module() with that freed object. Reachability requires a GC2235 probe failure; the published record identifies no code-execution or disclosure consequence.
