Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.34 (Operating System). It has been classified as problematic. This affects an unknown code block of the file include/linux/init_task.h of the component Swapper. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

include/linux/init_task.h in the Linux kernel before 2.6.35 does not prevent signals with a process group ID of zero from reaching the swapper process, which allows local users to cause a denial of service (system crash) by leveraging access to this process group.

The bug was discovered 05/27/2010. The weakness was shared 02/06/2017 (Website). The advisory is shared at ftp.naist.jp. This vulnerability is uniquely identified as CVE-2010-5328 since 01/20/2017.
