What is CVE-2016-10467?

CVE-2016-10467 is a critical vulnerability in Qualcomm Sd 205 Firmware, published on 18 Apr 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official 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.

Weakness: CWE-320
