CVE-2026-45996
In the Linux kernel, the following vulnerability has been resolved:
spi: imx: fix use-after-free on unbind
The SPI subsystem frees the controller and any subsystem allocated driver data as part of deregistration (unless the allocation is device managed).
Take another reference before deregistering the controller so that the driver data is not freed until the driver is done with it.
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: 0.17%
- Percentil entre todas las CVEs puntuadas: 6
- Fecha de la puntuación: 5/10/2026
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).
