Two buffer overflow vulnerabilities were discovered in the Trusted Platform Module (TPM) 2.0 reference library specification, currently at Level 00, Revision 01.59 November 2019. An attacker who has access to a TPM-command interface can send maliciously-crafted commands to the module and trigger these vulnerabilities. This allows either read-only access to sensitive data or overwriting of normally protected data that is only available to the TPM (e.g., cryptographic keys).

As the amount of new memory-unsafe code entering Android has decreased, so too has the number of memory safety vulnerabilities. From 2019 to 2022 it has dropped from 76% down to 35% of Android’s total vulnerabilities. 2022 is the first year where memory safety vulnerabilities do not represent a majority of Android’s vulnerabilities.
