CVE-2026-72207

Estado: RecibidaCrítica (9.8)—

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

ntfs: not change 0-byte $DATA attribute to non-resident

When ntfs_resident_attr_resize() cannot grow a resident attribute in place, it retries after converting other resident attributes to non-resident to free space in the MFT recrord.

Do not select zero-length resident $DATA attributes for this conversion. fsck treats 0-byte non-resident $DATA attribute as corruptions.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 9.8

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: 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).
