  "description": "In the Linux kernel, the following vulnerability has been resolved:  pinctrl: spacemit: fix NULL check in spacemit_pin_set_config  spacemit_pin_set_config() looks up the per-pin descriptor with spacemit_get_pin() then checks the wrong variable for failure:  \tconst struct spacemit_pin *spin = spacemit_get_pin(pctrl, pin); \t... \tif (!pin) \t\treturn -EINVAL;  \treg = spacemit_pin_to_reg(pctrl, spin-\u003Epin);  pin is an unsigned int pin id, where 0 (GPIO_0 / gmac0_rxdv on K3) is a valid pin, so rejecting it here drops the PAD config write for the first pin of every group. On K3 Pico-ITX the GMAC RGMII group lists pin 0 as its first entry, so its drive-strength / bias configuration was silently ignored.  The intended guard is against spacemit_get_pin() returning NULL when the pin id isn\u0027t in the SoC\u0027s pin table. Check spin instead, which both restores PAD setup for pin 0 and prevents a NULL deref on spin-\u003Epin.",
