CVE-2022-46892In Ampere AltraMax and Ampere Altra before 2.10c, improper access controls allows the OS to reinitialize a disabled root complex.
CVE-2022-32295On Ampere Altra and AltraMax devices before SRP 1.09, the Altra reference design of UEFI accesses allows insecure access to SPI-NOR by the OS/hypervisor component.
CVE-2022-37459Ampere Altra devices before 1.08g and Ampere Altra Max devices before 2.05a allow attackers to control the predictions for return addresses and potentially hijack code flow to execute arbitrary code via a side-channel attack, aka a "Retbleed" issue.
CVE-2021-45454Ampere Altra before SRP 1.08b and Altra Max before SRP 2.05 allow information disclosure of power telemetry via HWmon.
CVE-2022-35888Ampere Altra and Ampere Altra Max devices through 2022-07-15 allow attacks via Hertzbleed, which is a power side-channel attack that extracts secret information from the CPU by correlating the power consumption with data being processed on the system.
CVE-2022-25368Spectre BHB is a variant of Spectre-v2 in which malicious code uses the shared branch history (stored in the CPU BHB) to influence mispredicted branches in the victim's hardware context. Speculation caused by these mispredicted branches can then potentially be used to cause cache allocation, which can then be used to infer information that should be protected.
