|---|---|---|---|---|---|
| CVE-2021-26348 | 1 Amd | 46 Epyc 72f3, Epyc 72f3 Firmware, Epyc 7313 and 43 more | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity. | |||||
| CVE-2021-26347 | 1 Amd | 98 Epyc 7002, Epyc 7002 Firmware, Epyc 7232p and 95 more | 2024-11-21 | 4.7 MEDIUM | 4.7 MEDIUM |
| Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service. | |||||
| CVE-2021-26345 | 1 Amd | 180 Epyc 7203, Epyc 7203 Firmware, Epyc 7203p and 177 more | 2024-11-21 | N/A | 1.9 LOW |
| Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service. | |||||
| CVE-2021-26343 | 1 Amd | 48 Epyc 7003, Epyc 7003 Firmware, Epyc 72f3 and 45 more | 2024-11-21 | N/A | 5.5 MEDIUM |
| Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure. | |||||
| CVE-2021-26342 | 1 Amd | 76 Epyc 7001, Epyc 7001 Firmware, Epyc 7251 and 73 more | 2024-11-21 | 2.1 LOW | 3.3 LOW |
| In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest memory contents. Users of SEV-ES/SEV-SNP guest VMs are not impacted by this vulnerability. | |||||
| CVE-2021-26339 | 1 Amd | 168 Epyc 72f3, Epyc 72f3 Firmware, Epyc 7313 and 165 more | 2024-11-21 | 4.9 MEDIUM | 5.5 MEDIUM |
| 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. | |||||
| CVE-2021-26332 | 1 Amd | 46 Epyc 72f3, Epyc 72f3 Firmware, Epyc 7313 and 43 more | 2024-11-21 | 6.6 MEDIUM | 7.1 HIGH |
| Failure to verify SEV-ES TMR is not in MMIO space, SEV-ES FW could result in a potential loss of integrity or availability. | |||||
| CVE-2021-26328 | 1 Amd | 48 Epyc 7003, Epyc 7003 Firmware, Epyc 72f3 and 45 more | 2024-11-21 | N/A | 4.4 MEDIUM |
| Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests. | |||||
| CVE-2021-26324 | 1 Amd | 46 Epyc 72f3, Epyc 72f3 Firmware, Epyc 7313 and 43 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| A bug with the SEV-ES TMR may lead to a potential loss of memory integrity for SNP-active VMs. | |||||
| CVE-2021-26316 | 1 Amd | 294 Athlon 3050ge, Athlon 3050ge Firmware, Athlon 3150g and 291 more | 2024-11-21 | N/A | 7.8 HIGH |
| Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution. | |||||
| CVE-2023-20578 | 1 Amd | 210 Epyc 7001, Epyc 7001 Firmware, Epyc 7203 and 207 more | 2024-10-02 | N/A | 6.4 MEDIUM |
| A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution. | |||||
