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

dm-integrity: don't increment hash_offset twice

Detalles técnicos trazas, registros y código del informe original

hash_offset is already incremented in the loop "for (i = 0; i < to_copy;
i++, ts--)". Do not increment it again.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L
Puntuación base: 7.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.55%
Percentil entre todas las CVEs puntuadas: 44
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).
