A vulnerability exists in the logic handling periodic Viridian STIMERs where a division operation uses a user-controlled divisor without validation. This divisor can be set to zero, causing a divide-by-zero (#DE) fault. The issue results in a denial of service condition due to the fault triggered by the invalid division.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-62431) involves the handling of periodic Viridian STIMERs where the divisor used in a division operation is controlled by user input and is not checked for zero. Setting this divisor to zero causes a divide-by-zero exception (#DE fault), leading to a denial of service. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, no confidentiality or integrity impact, but high availability impact. No patch or remediation information is provided in the data.
Potential Impact
Exploitation of this vulnerability causes a denial of service condition by triggering a divide-by-zero fault. There is no impact on confidentiality or integrity, but availability is severely affected due to the fault condition.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid exposing the vulnerable interface to untrusted users or inputs that could trigger the divide-by-zero condition.
