What is CVE-2022-43778?

The identified Time-of-Check to Time-of-Use (TOCTOU) vulnerabilities in the HP BIOS can potentially allow an attacker to execute arbitrary code, leading to risks such as denial of service and unauthorized information disclosure. These vulnerabilities arise from the timing differences between when a check is made on the state of a variable and when the variable is used, which can be exploited to manipulate system behavior.
