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.
