CVE-2023-53764

Estado: AplazadaAlta (8.8)—

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

wifi: ath12k: Handle lock during peer_id find

ath12k_peer_find_by_id() requires that the caller hold the ab->base_lock. Currently the WBM error path does not hold the lock and calling that function, leads to the following lockdep_assert()in QCN9274:

Handle spin lock/unlock in WBM error path to hold the necessary lock expected by ath12k_peer_find_by_id().

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0-03171-QCAHKSWPL_SILICONZ-1

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.

AV:A (red adyacente) sugiere T1210, pero es un parche de sincronización en driver WiFi sin explotación activa ni cadena clara de ataque remoto. El DoS potencial por condición de carrera justifica T1499.004.

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.
