CVE-2023-48267

Overview

CVE-2023-48267 describes an improper buffer restrictions vulnerability within certain Intel(R) System Security Report and System Resources Defense firmware components [1][2]. The root cause is insufficient boundary checking when handling data, which can lead to memory corruption under specific conditions.

Exploitation

An attacker must have local access and already hold a privileged user role on the affected system [1][2]. No network vector is required; the attack is launched from the local host. The vulnerability can be triggered by a locally authenticated user who sends crafted input to the vulnerable firmware interface.

Impact

Successful exploitation allows the attacker to further escalate their privileges beyond the initial privilege level, potentially gaining full control over the system firmware [1][2]. Given the high CVSS base score of 7.9, this poses a significant risk to affected platforms.

Mitigation

Dell and Intel have released firmware updates to remediate this vulnerability, as detailed in Intel advisory INTEL-SA-01203 and Dell security advisory DSA-2025-002 [1][2]. Affected Dell client platforms include several Alienware, OptiPlex, Precision, and Latitude models; users should apply the BIOS updates listed in the advisory to mitigate the risk [1].
