Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel (Operating System). Affected is the function sys_get_thread_area of the file process.c. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The sys_get_thread_area function in process.c in Linux 2.6 before 2.6.12.4 and 2.6.13 does not clear a data structure before copying it to userspace, which might allow a user process to obtain sensitive information.
