CVE-2006-5755

Publication date 31 December 2006

Last updated 24 July 2024

Ubuntu priority

Unknown

Why this priority?

Linux kernel before 2.6.18, when running on x86_64 systems, does not properly save or restore EFLAGS during a context switch, which allows local users to cause a denial of service (crash) by causing SYSENTER to set an NT flag, which can trigger a crash on the IRET of the next task.
