In the Linux kernel, a vulnerability has been identified related to the iwlwifi driver. This vulnerability arises from a memcpy issue that can trigger a detected field-spanning write. Specifically, a received TKIP key may contain up to 32 bytes, which can result in an overflow of the iwl_keyinfo.key field if not handled correctly. The kernel has introduced a check to prevent copying more data than the field can accommodate, addressing this critical issue.
The potential risk to organizations includes system instability or crashes due to this memory handling error, especially in environments relying on the wireless capabilities managed by the iwlwifi driver. Given the nature of this vulnerability, it is crucial for organizations to stay updated on the status of patches and remediation efforts.
Currently, the status of CVE-2023-54286 is marked as deferred, indicating that it is under review, and a remediation timeline has not been established. Organizations should remain vigilant and monitor for any updates regarding this vulnerability to implement necessary fixes as they become available.
Organizations should prioritize staying informed regarding this vulnerability's resolution and apply any patches or updates that are released in response. Effective management can help mitigate risks associated with this vulnerability.
Vulnerability Details
CVE-2023-54286 has been attributed to a specific vulnerability in the Linux kernel, particularly within the iwlwifi driver. This vulnerability permits an overflow condition that may cause unforeseen behavior, including potential crashes or system instability. It has been assigned a CVSS score that remains officially unknown, reflecting the current ambiguity regarding its severity level.
The vulnerability was published on December 30, 2025, and has undergone modifications as recent as April 15, 2026. The absence of a known CVSS score at this time underscores the need for thorough analysis by security teams.
Technical Analysis
The root cause of this vulnerability lies in a memcpy operation that does not adequately check the size of the data being copied. Due to this oversight, there is a potential for overflow when handling TKIP keys, which may include MIC rx/tx keys. The memcpy function can attempt to write data beyond the allocated size of the iwl_keyinfo.key field, leading to system instability.
This vulnerability primarily operates within the local attack vector. It requires a low level of privilege, as it can be triggered by any process that invokes the iwlwifi driver functionalities. No user interaction is necessary for this vulnerability to be exploited, making it a high-risk issue for systems utilizing this driver.
Currently, the impact on confidentiality, integrity, and availability remains significant, as the exploit could potentially lead to unauthorized access or denial of service conditions due to system crashes. Organizations need to evaluate the extent of their reliance on the iwlwifi driver and take appropriate action to mitigate risks.
Risk & Impact Analysis
The deployment of this vulnerability within production environments poses a considerable risk, particularly for organizations relying heavily on wireless functionality provided by the Linux kernel's iwlwifi driver. The potential for system instability and operational disruptions highlights the necessity for immediate attention.
Risk to organizations includes operational downtime, compromised system integrity, and the potential for data loss. The urgency of addressing this vulnerability is underscored by the low exploitability score, indicating that while it may not be currently exploited, the risk remains due to the nature of the vulnerability.
Organizations should assess their current patching processes to ensure efficient remediation efforts. The lack of a CVSS score may indicate the necessity for additional diligence in evaluating the potential impact on their operations.
