Overview
CVE-2026-98480 is a known-severity vulnerability. It was published on October 18, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
nfc: trf7970a: power down on startup RX gain failure
trf7970a_startup() powers up the device before applying the optional RX
gain reduction. If the register read or write fails, it returns without
undoing that power-up. Probe's unwind only drops the separate regulator
references acquired by probe, leaving the additional VIN enable from
startup unbalanced. The system resume caller also has no power-down on
this error.
Call trf7970a_power_down() before returning the RX gain error to deassert
the enable GPIOs, release the startup VIN reference and restore the
powered-off state. Runtime PM has not been enabled yet, so the full
shutdown helper is not appropriate here. Preserve the original SPI error.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

How can CyberStrike help with CVE-2026-98480?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-98480 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
