CWE Code: 119
Vulnerability Type: privilege_escalation
CVSS Score: 4.6
CWE Name:  Improper Restriction of Operations within the Bounds of a Memory Buffer
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.
Access Authentication: NONE
Access Complexity: LOW
Access Vector: LOCAL
Impact (C/I/A): PARTIAL/PARTIAL/PARTIAL
