CVEs (9)

  • CVE-2023-20520CriMay 9, 2023
    risk 0.64cvss 9.8epss 0.01

    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-2021-46769HigMay 9, 2023
    risk 0.57cvss 8.8epss 0.01

    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-2021-26356HigMay 9, 2023
    risk 0.48cvss 7.4epss 0.00

    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-2023-20527MedJan 11, 2023
    risk 0.42cvss 6.5epss 0.01

    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-2023-20525MedJan 11, 2023
    risk 0.42cvss 6.5epss 0.01

    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-2021-46792MedMay 9, 2023
    risk 0.38cvss 5.9epss 0.00

    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-2023-20521LowNov 14, 2023
    risk 0.21cvss 3.3epss 0.00

    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-2021-46766LowNov 14, 2023
    risk 0.16cvss 2.5epss 0.00

    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-2023-20526LowNov 14, 2023
    risk 0.12cvss 1.9epss 0.00

    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.
