Discussion

Linux Kernel Random Number Generator Local Denial of Service and Privilege Escalation Vulnerability

The Linux kernel is prone to a local vulnerability that may result in a denial of service or privilege escalation. This issue stems from a stack-based overflow in kernel memory.

Successfully exploiting this issue allows local attackers to trigger kernel crashes, denying service to legitimate users. In certain circumstances, attackers may also gain elevated privileges. The attacker may require partial administrative access via granular assignments of superuser privileges.

Linux kernel versions prior to 2.6.22.3 are affected by this issue.
