MediumMetricsAV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
Name of the Vulnerable Software and Affected Versions
Intel(R) Processors (affected versions not specified)
Description
The issue is related to an unprotected alternative channel of return branch target prediction in some Intel(R) Processors, which may allow an authorized user to potentially enable information disclosure via local access. The RSBA behavior allows alternate branch predictors to be used by near RET instructions when the RSB is empty. When eIBRS is enabled, the predicted target of these alternate predictors are restricted to those belonging to the indirect branch predictor entries of the current prediction domain.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
