FKIE_CVE-2006-5173
Vulnerability from fkie_nvd - Published: 2006-10-17 22:07 - Updated: 2026-04-23 00:35
Severity
Summary
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.
