A vulnerability exists in SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer(QWORD values for CommBuffer). Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
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. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. Public exploit code available and EPSS exploitation probability 46.0%.
