CVE-2023-53017

Estado: ModificadaMedia (5.5)—

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

Bluetooth: hci_sync: fix memory leak in hci_update_adv_data()

When hci_cmd_sync_queue() failed in hci_update_adv_data(), inst_ptr is not freed, which will cause memory leak, convert to use ERR_PTR/PTR_ERR to pass the instance to callback so no memory needs to be allocated.

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).
