Detailsinfo

A vulnerability was found in Little Kernel Bootloader (version now known). It has been declared as critical. This vulnerability affects the function image_verify. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The image_verify function in platform/msm_shared/image_verify.c in the Little Kernel (LK) bootloader, as distributed with Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not check whether a certain digest size is consistent with the RSA_public_decrypt API specification, which makes it easier for attackers to bypass boot-image authentication requirements via trailing data.
