CVE-2026-72500

Estado: RecibidaAlta (8.8)—

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

RDMA/bnxt_re: Free SRQ toggle page after firmware teardown

Free the toggle page only after firmware teardown completes so that an NQ interrupt arriving during bnxt_qplib_destroy_srq() won't write the toggle values to an already-freed page. Move free_page() after bnxt_qplib_destroy_srq().

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 8.8

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).
