| CVE | Vendor / Product | Sev | Risk | CVSS | EPSS | KEV | Published | Description |
|---|---|---|---|---|---|---|---|---|
| CVE-2023-20520 | Cri | 0.64 | 9.8 | 0.01 | May 9, 2023 | Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution. | ||
| CVE-2021-46769 | Hig | 0.57 | 8.8 | 0.01 | May 9, 2023 | Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution. | ||
| CVE-2021-26356 | Hig | 0.48 | 7.4 | 0.00 | May 9, 2023 | A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to memory potentially resulting in S3 data corruption and information disclosure. | ||
| CVE-2023-20527 | Med | 0.42 | 6.5 | 0.01 | Jan 11, 2023 | Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service. | ||
| CVE-2023-20525 | Med | 0.42 | 6.5 | 0.01 | Jan 11, 2023 | Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service. | ||
| CVE-2021-46792 | Med | 0.38 | 5.9 | 0.00 | May 9, 2023 | Time-of-check Time-of-use (TOCTOU) in the BIOS2PSP command may allow an attacker with a malicious BIOS to create a race condition causing the ASP bootloader to perform out-of-bounds SRAM reads upon an S3 resume event potentially leading to a denial of service. | ||
| CVE-2023-20521 | Low | 0.21 | 3.3 | 0.00 | Nov 14, 2023 | TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service. | ||
| CVE-2021-46766 | Low | 0.16 | 2.5 | 0.00 | Nov 14, 2023 | Improper clearing of sensitive data in the ASP Bootloader may expose secret keys to a privileged attacker accessing ASP SRAM, potentially leading to a loss of confidentiality. | ||
| CVE-2023-20526 | Low | 0.12 | 1.9 | 0.00 | Nov 14, 2023 | Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality. |
