CVE-2016-10467 is rated critical with a CVSS v3.0 base score of 9.8 and NVD lists 16 affected products, including Qualcomm SD 210 Firmware. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile and Snapdragon Mobile SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 615/16/SD 415, SD 617, SD 650/52, SD 800, SD 808, SD 820, and SD 820A, function ce_pkcs1_pss_padding_verify_auto_recover_saltlen assumes that the size of the encoded message is equal to the size of the RSA modulus. This assumption is true for most RSA keys, but it fails when modulus_bitlen % 8 == 1.
