GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2007-3732 (GCVE-0-2007-3732)

Vulnerability from cvelistv5 – Published: 2019-11-07 21:31 – Updated: 2024-08-07 14:28
VLAI
Summary
In Linux 2.6 before 2.6.23, the TRACE_IRQS_ON function in iret_exc calls a C function without ensuring that the segments are set properly. The kernel's %fs needs to be restored before the call in TRACE_IRQS_ON and before enabling interrupts, so that "current" references work. Without this, "current" used in the window between iret_exc and the middle of error_code where %fs is reset, would crash.
Severity
5.5 (Medium)
