CVE-2025-38292

Estado: ModificadaAlta (7.1)—

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

wifi: ath12k: fix invalid access to memory

In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean is_continuation is part of rxcb. Currently, after freeing the skb, the rxcb->is_continuation accessed again which is wrong since the memory is already freed. This might lead use-after-free error.

Hence, fix by locally defining bool is_continuation from rxcb, so that after freeing skb, is_continuation can be used.

Compile tested only.

CVSS

Probabilidad de explotación (EPSS)

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso local (AV:L) sin interacción del usuario en kernel Linux; CWE-125 (out-of-bounds read) permite lectura/ejecución de código. Pista sugiere T1068 como explotación.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
