A vulnerability in the Linux kernel, which can be exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to the kernel not zero-extending x86_64 registers after ptrace in the 32bit entry path in arch/x86_64/ia32/ia32entry.S on x86_64 platforms.

The vulnerability is reported in versions prior to 2.4.35.3 and 2.6.22.7.

If your server is on x86_64 and kernel prior to 2.4.35.3 and 2.6.22.7, please open a support ticket for updating the kernel.
