CVE-2025-21982

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: nuvoton: npcm8xx: Add NULL check in npcm8xx_gpio_fw

devm_kasprintf() calls can return null pointers on failure. But the return values were not checked in npcm8xx_gpio_fw(). Add NULL check in npcm8xx_gpio_fw(), to handle kernel NULL pointer dereference error.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
