Linux · Linux Kernel · CVE-2024-40944
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to a bug in the x86/kexec component of the Linux kernel, where the call to `cc platform has()` triggers a fault and system crash if call depth tracking is active. This occurs because the GS segment has been reset by `load segments()` and `GS BASE` is now 0, but call depth tracking uses per-CPU variables to operate. The fix involves calling `cc platform has()` earlier in the function when GS is still valid.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
