CVE-2026-68091 Vulnerability Summary
CVE-2026-68091: In the Linux kernel, the following vulnerability has been resolved: HID: wacom: stop hardware after post-start probe failures wacom_parse_and_register() starts HID hardware before registering inputs and initializing pad LEDs/remotes. Those later steps can fail, but their error paths currently release Wacom resources without stopping the HID hardware. Route post-hid_hw_start() failures through hid_hw_stop() before releasing driver resources. This issue was identified during our ongoing static-analysis research while reviewing kernel code.
Assessing the Risk of CVE-2026-68091
Access Complexity Graph
The exploitability of CVE-2026-68091 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-2026-68091
No exploitability data is available for CVE-2026-68091.
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-2026-68091, 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.
