CVE-2007-3105: Linux Kernel

Medium severity, CVSS 4.6. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 2.6.22
