Improper conditions check in the voltage modulation interface for some Intel Xeon Scalable Processors may allow a privileged user to potentially enable denial of service via local access.(CVE-2019-11139)
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.(CVE-2019-11135)
Affected Packages:
microcode_ctl, kernel
Note:
