CVE-2022-33905

Estado: ModificadaAlta (7)—

DMA transactions which are targeted at input buffers used for the AhciBusDxe software SMI handler could cause SMRAM corruption (a TOCTOU attack). DMA transactions which are targeted at input buffers used for the software SMI handler used by the AhciBusDxe driver could cause SMRAM corruption through a TOCTOU attack. This issue was discovered by Insyde engineering based on the general description provided by Intel's iSTARE group, Fixed in kernel 5.2: 05.27.23, kernel 5.3: 05.36.23, kernel 5.4: 05.44.23, kernel 5.5: 05.52.23 https://www.insyde.com/security-pledge/SA-2022047

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).
