2022-03-08 18:00

HP has disclosed 16 high-impact UEFI firmware vulnerabilities that could allow threat actors to infect devices with malware that gain high privileges and remain undetectable by installed security software.

SSM. CVE-2021-23924: heap buffer overflow leading to arbitrary code execution.

CVE-2021-23931: heap buffer overflow leading to arbitrary code execution.

CVE-2021-23934: memory corruption leading to arbitrary code execution(CVSS - 8.2). DXE. CVE-2021-39297: stack buffer overflow leading to arbitrary code execution.

CVE-2021-39299: stack buffer overflow leading to arbitrary code execution.

One of the flaws, CVE-2021-39298, was identified as an AMD reference code vulnerability, and as such, it doesn't affect only HP but numerous computer vendors who use the particular firmware driver.
