|---|---|---|---|---|---|---|
| CVE-2025-62864 | Ampere AmpereOne AC03 devices before 3.5.9.3, AmpereOne AC04 devices before 4.4.5.2, and AmpereOne M devices before 5.4.5.1 allow an incorrectly formed SMC call to UEFI-MM MMCommunicate service that could result in an out-of-bounds write within the UEFI-MM Secure Partition context. | [email protected] | 9.8 | 0.31% | 2025-12-16 | 2026-06-17 |
| CVE-2025-62863 | Ampere AmpereOne AC03 devices before 3.5.9.3, AmpereOne AC04 devices before 4.4.5.2, and AmpereOne M devices before 5.4.5.1 allow an incorrectly formed SMC call to UEFI-MM PCIe driver that could result in an out-of-bounds write within PCIe driver’s S-EL0 address space. | [email protected] | 9.8 | 0.31% | 2025-12-16 | 2026-06-17 |
| CVE-2025-62862 | Ampere AmpereOne AC03 devices before 3.5.9.3, AmpereOne AC04 devices before 4.4.5.2, and AmpereOne M devices before 5.4.5.1 allow an incorrectly formed SMC call to UEFI-MM Boot Error Record Table driver that could result in (1) an out-of-bounds read which leaks Secure-EL0 information to a process running in Non-Secure state or (2) an out-of-bounds write which corrupts Secure or Non-Secure memory, limited to memory mapped to UEFI-MM Secure Partition by the Secure Partition Manager. | [email protected] | 4.6 | 0.10% | 2025-12-16 | 2026-06-17 |
| CVE-2022-46892 | In Ampere AltraMax and Ampere Altra before 2.10c, improper access controls allows the OS to reinitialize a disabled root complex. | [email protected] | 9.8 | 0.62% | 2023-02-15 | 2026-06-17 |
| CVE-2022-35888 | Ampere 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. | [email protected] | 6.5 | 0.57% | 2022-09-29 | 2026-06-17 |
| CVE-2022-37459 | Ampere 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. | [email protected] | 7.8 | 0.17% | 2022-08-17 | 2026-06-17 |

| CVE-2022-32295 | On 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. | [email protected] | 9.8 | 1.05% | 2022-07-01 | 2026-06-17 |
| CVE-2022-25368 | Spectre 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. | [email protected] | 4.7 | 0.29% | 2022-03-10 | 2026-06-17 |
