Researchers discuss it in same breath as BlackLotus and MosaicRegressor
A new vulnerability in UEFI firmware is threatening the security of a wide range of Intel chip families in a similar fashion to BlackLotus and others like it.
The vulnerability is located in the Trusted Platform Module configuration and centers around an unsafe variable , the abuse of which could lead to a buffer overflow, privilege escalation, and code execution. Given that CVE-2024-0762 is located in the code that handles the configuration of the TPM, simply having a TPM in a device, which is designed to increase its security and prevent untrustworthy boot processes from executing, won't be enough to prevent successful exploits.shows a wide range of notebooks and ThinkPads were affected. Lenovo owners, take a look and patch up if needed.
UEFI exploits always tend to raise the industry's eyebrows as they often allow silent backdoors into the lowest, most privileged levels of a system and exploits are notoriously difficult to detect.are previous examples of UEFI flaws that made security pros sweat. This flaw, which Eclypsium dubbed"UEFICanHazBufferOverflow" , is being hyped as a finding of similar significance.
