- Summary
- [none]
- Details
-
An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. The xenfailsafecallback entry point in arch/x86/entry/entry_64.S does not properly maintain RBX, which allows local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges.
