Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Processor optimization removal or modification of security-critical code for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Improper access control for some 3rd Generation Intel(R) Xeon(R) Scalable Processors before BIOS version MR7, may allow a local attacker to potentially enable information disclosure via local access.
Out of bounds read under complex microarchitectural condition in memory subsystem for some Intel Atom(R) Processors may allow authenticated user to potentially enable information disclosure or cause denial of service via network access.
Insufficient control flow management in some Intel(R) Processors may allow an authenticated user to potentially enable a denial of service via local access.
Improper initialization of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Hardware allows activation of test or debug logic at runtime for some Intel(R) processors which may allow an unauthenticated user to potentially enable escalation of privilege via physical access.
Incomplete cleanup in some Intel(R) VT-d products may allow an authenticated user to potentially enable escalation of privilege via local access.
Domain-bypass transient execution vulnerability in some Intel Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Observable timing discrepancy in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.
Improper removal of sensitive information before storage or transfer in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
USN-4385-1 provided updated Intel Processor Microcode. Unfortunately, that update prevented certain processors in the Intel Skylake family (06_4EH) from booting successfully. Additonally, on Ubuntu 20.04 LTS, late loading of microcode was enabled, which could lead to system instability. This update reverts the microcode update for the Skylake processor family and disables the late loading option on Ubuntu 20.04 LTS. Please note that the 'dis_ucode_ldr' kernel command line option can be added in the boot menu to disable microcode loading for system recovery. We apologize for the inconvenience. Original advisory details: It was discovered
Cleanup errors in some data cache evictions for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
Cleanup errors in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
