CVE-2020-0543: Medium severity Intel Celeron 1000m vulnerability
Published Apr 23, 2020
·Updated
A new domain bypass transient execution attack known as Special Register Buffer Data Sampling (SRBDS) has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU. An unprivileged, local attacker can use this flaw to infer values returned by affected instructions known to be commonly used during cryptographic operations that rely on uniqueness, secrecy, or both.
Other sources
Certain microprocessor operations (including RDRAND and RDSEED) are implemented using micro-architecture specific Special Register Reads (SRR). On certain client and E3 processors, the data returned by these SRR operations may be inferred, even on another core. Cleanup errors from specific special register read operations may allow an authenticated user to potentially enable information disclosure via local access.
— Red Hat
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.
