CVE-2025-37889 Vulnerability Summary

CVE-2025-37889: In the Linux kernel, the following vulnerability has been resolved: ASoC: ops: Consistently treat platform_max as control value This reverts commit 9bdd10d57a88 ("ASoC: ops: Shift tested values in snd_soc_put_volsw() by +min"), and makes some additional related updates. There are two ways the platform_max could be interpreted; the maximum register value, or the maximum value the control can be set to. The patch moved from treating the value as a control value to a register one. When the patch was applied it was technically correct as snd_soc_limit_volume() also used the register interpretation. However, even then most of the other usages treated platform_max as a control value, and snd_soc_limit_volume() has since been updated to also do so in commit fb9ad24485087 ("ASoC: ops: add correct range check for limiting volume"). That patch however, missed updating snd_soc_put_volsw() back to the control interpretation, and fixing snd_soc_info_volsw_range(). The control interpretation makes more sense as limiting is typically done from the machine driver, so it is appropriate to use the customer facing representation rather than the internal codec representation. Update all the code to consistently use this interpretation of platform_max. Finally, also add some comments to the soc_mixer_control struct to hopefully avoid further patches switching between the two approaches.

Assessing the Risk of CVE-2025-37889

Access Complexity Graph

The exploitability of CVE-2025-37889 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-2025-37889

No exploitability data is available for CVE-2025-37889.

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-2025-37889, 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.
