CVE-2025-40262

Estado: AplazadaAlta (7.8)—

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

Input: imx_sc_key - fix memory corruption on unload

This is supposed to be "priv" but we accidentally pass "&priv" which is an address in the stack and so it will lead to memory corruption when the imx_sc_key_action() function is called. Remove the &.

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).
