IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure. Rated medium severity (CVSS 6.5), this vulnerability is low attack complexity. No vendor patch available.
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. Rated medium severity (CVSS 6.5), this vulnerability is low attack complexity. No vendor patch available.
A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA read from invalid DRAM address to SRAM resulting in SMU not servicing further requests. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
Insufficient bounds checking in System Management Unit (SMU) may cause invalid memory accesses/updates that could result in SMU hang and subsequent failure to service any further requests from other. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
