CVE-2023-54292

Estado: AplazadaCrítica (9.8)—

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

RDMA/irdma: Fix data race on CQP request done

KCSAN detects a data race on cqp_request->request_done memory location which is accessed locklessly in irdma_handle_cqp_op while being updated in irdma_cqp_ce_handler.

Annotate lockless intent with READ_ONCE/WRITE_ONCE to avoid any compiler optimizations like load fusing and/or KCSAN warning.

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.

Data race en driver RDMA del kernel Linux (AV:N, acceso remoto). Vector CVSS crítico (C:H/I:H/A:H) sugiere DoS y escalada, pero es un bug de sincronización sin explotación activa documentada.

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.
