CVE-2006-5173
2.1 · LOWOverview
CVE-2006-5173 is a low-severity vulnerability affecting linux linux_kernel. It was published on October 17, 2006 and has a CVSS 2.0 base score of 2.1 (LOW).
This vulnerability has a CVSS 2.0 base score of 2.1, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Linux kernel does not properly save or restore EFLAGS during a context switch, or reset the flags when creating new threads, which allows local users to cause a denial of service (process crash), as demonstrated using a process that sets the Alignment Check flag (EFLAGS 0x40000), which triggers a SIGBUS in other processes that have an unaligned access.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
