Dell has just rolled-out an urgent BIOS update (version 1.3.4) for its popular XPS 15 9560-series notebook. The BIOS update mainly seems to be in response to the recent discovery of a serious bug in the microcode of Intel's Kaby Lake and Skylake architectures.

Last week we reported on a serious issue with Intel's hyperthreaded 6th and 7th-generation chips. The bug, which could result in system instability and corruption or loss of data, requires a BIOS or UEFI update to fix the bug.

Fixed a potential security issue with Bootguard code integrity chaining enforcement".
Fixed a potential security issue with the Support Assist PreBoot feature
Updated processor microcode
Update Computrace 957
Update PD firmware
