CVE-2021-26384 |
A malformed SMI (System Management Interface) command may allow an attacker to establish a corrupted SMI Trigger Info data structure, potentially leading to out-of-bounds memory reads and writes when triggering an SMI resulting in a potential loss of resources. Published: July 14, 2022; 4:15:08 PM -0400 |

V4.0:(not available) V3.1: 6.5 MEDIUM V2.0: 4.0 MEDIUM |
CVE-2021-26386 |
A malicious or compromised UApp or ABL may be used by an attacker to issue a malformed system call to the Stage 2 Bootloader potentially leading to corrupt memory and code execution. Published: May 12, 2022; 3:15:48 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 7.2 HIGH |
CVE-2021-26368 |
Insufficient check of the process type in Trusted OS (TOS) may allow an attacker with privileges to enable a lesser privileged process to unmap memory owned by a higher privileged process resulting in a denial of service. Published: May 12, 2022; 3:15:48 PM -0400 |
V4.0:(not available) V3.1: 4.4 MEDIUM V2.0: 4.9 MEDIUM |
CVE-2021-26363 |
A malicious or compromised UApp or ABL could potentially change the value that the ASP uses for its reserved DRAM, to one outside of the fenced area, potentially leading to data exposure. Published: May 12, 2022; 3:15:48 PM -0400 |
V4.0:(not available) V3.1: 4.4 MEDIUM V2.0: 3.6 LOW |
CVE-2021-26317 |
