CVE-2022-49487

Estado: ModificadaMedia (5.5)—

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

mtd: rawnand: intel: fix possible null-ptr-deref in ebu_nand_probe()

It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.

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).
