CVE-2023-53510

Estado: ModificadaAlta (7.8)—

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

scsi: ufs: core: Fix handling of lrbp->cmd

ufshcd_queuecommand() may be called two times in a row for a SCSI command before it is completed. Hence make the following changes:

- In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.15%
Percentil entre todas las CVEs puntuadas: 4
Fecha de la puntuación: 6/10/2026

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).
