AI-suggested
A fix has been implemented in the Linux kernel to call trf7970a_power_down() on RX gain errors during startup, ensuring proper power down and resource release. Users should update to the fixed kernel versions identified by the commits d2acbde7e67df44efa8f0963462d1192e7694ffc, cc444e4ad43461374dd128573eccb8979d2adb4c, or 6ef70d790425e76b42c69e416ee78c62bdc37d00. No additional mitigation is required.
Description
A vulnerability in the Linux kernel's NFC driver for the trf7970a device causes improper power down on startup when an RX gain register read or write fails. This leads to an unbalanced power state due to failure to undo device power-up, potentially causing resource mismanagement.
