Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value.
AnalysisAI
Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. Affected products include: Openbsd.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate arithmetic operations, use safe integer libraries, check bounds before allocation.
