Title: Linux Kernel VDSO Unspecified Privilege Escalation Vulnerability
Severity: HIGH
Description:
The Linux Kernel is prone to a local privilege-escalation vulnerability.
This issue stems from insufficient bounds checking in the 'syscall()' and 'syscall_nopage32()' function calls in the Virtual Dynamic Shared Object (VDSO) implementation. A local attacker may exploit this issue to gain elevated privileges or to create a denial-of-service condition.
Versions prior to the Linux kernel 2.6.20-git5 are vulnerable.
