FKIE_CVE-2007-3105
Vulnerability from fkie_nvd - Published: 2007-07-27 21:30 - Updated: 2026-06-16 22:41
Severity
Summary
Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving "bound check ordering". NOTE: this issue might only cross privilege boundaries in environments that have granular assignment of privileges for root.
