CVE-2023-53715 Vulnerability Summary
CVE-2023-53715: In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: cfg80211: Pass the PMK in binary instead of hex Apparently the hex passphrase mechanism does not work on newer chips/firmware (e.g. BCM4387). It seems there was a simple way of passing it in binary all along, so use that and avoid the hexification. OpenBSD has been doing it like this from the beginning, so this should work on all chips. Also clear the structure before setting the PMK. This was leaking uninitialized stack contents to the device.
Assessing the Risk of CVE-2023-53715
Access Complexity Graph
The exploitability of CVE-2023-53715 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
Exploitability Analysis for CVE-2023-53715
No exploitability data is available for CVE-2023-53715.
Understanding AC and PR
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
CVSS Score Breakdown Chart
Above is the CVSS Sub-score Breakdown for CVE-2023-53715, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
