Discussion

Linux Kernel S/390 Copy_From_User Local Information Disclosure Vulnerability

The Linux kernel is prone to a local information-disclosure vulnerability on the S/390 architecture because the kernel fails to properly initialize kernel memory before returning it to user-space programs.

Successfully exploiting this issue allows local attackers to gain access to potentially sensitive information contained in kernel memory, aiding them in further attacks.

Linux kernel versions prior to 2.6.19-rc1 on the S/390 architecture are vulnerable to this issue.
