"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: spacemit: fix NULL check in spacemit_pin_set_config\n\nspacemit_pin_set_config() looks up the per-pin descriptor with\nspacemit_get_pin() then checks the wrong variable for failure:\n\n\tconst struct spacemit_pin *spin = spacemit_get_pin(pctrl, pin);\n\t...\n\tif (!pin)\n\t\treturn -EINVAL;\n\n\treg = spacemit_pin_to_reg(pctrl, spin->pin);\n\npin is an unsigned int pin id, where 0 (GPIO_0 / gmac0_rxdv on K3) is a\nvalid pin, so rejecting it here drops the PAD config write for the first\npin of every group. On K3 Pico-ITX the GMAC RGMII group lists pin 0 as\nits first entry, so its drive-strength / bias configuration was silently\nignored.\n\nThe intended guard is against spacemit_get_pin() returning NULL when the\npin id isn't in the SoC's pin table. Check spin instead, which both\nrestores PAD setup for pin 0 and prevents a NULL deref on spin->pin."
