"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: trf7970a: power down on startup RX gain failure\n\ntrf7970a_startup() powers up the device before applying the optional RX\ngain reduction. If the register read or write fails, it returns without\nundoing that power-up. Probe's unwind only drops the separate regulator\nreferences acquired by probe, leaving the additional VIN enable from\nstartup unbalanced. The system resume caller also has no power-down on\nthis error.\n\nCall trf7970a_power_down() before returning the RX gain error to deassert\nthe enable GPIOs, release the startup VIN reference and restore the\npowered-off state. Runtime PM has not been enabled yet, so the full\nshutdown helper is not appropriate here. Preserve the original SPI error.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code."
