CVE-2021-26351 |
Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA (Direct Memory Access) read/write from/to invalid DRAM address that could result in denial of service. Published: May 12, 2022; 2:16:53 PM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 4.9 MEDIUM |
CVE-2021-26339 |
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers. Published: May 11, 2022; 1:15:08 PM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 4.9 MEDIUM |
CVE-2021-26401 |
LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. Published: March 11, 2022; 1:15:11 PM -0500 |
V4.0:(not available) V3.1: 5.6 MEDIUM V2.0: 1.9 LOW |
CVE-2021-26341 |
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. Published: March 11, 2022; 1:15:10 PM -0500 |
V4.0:(not available) V3.1: 6.5 MEDIUM V2.0: 2.1 LOW |
CVE-2021-26337 |
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. Published: November 16, 2021; 2:15:08 PM -0500 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 2.1 LOW |
CVE-2021-26336 |
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 components. Published: November 16, 2021; 2:15:08 PM -0500 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 4.9 MEDIUM |
