CVE-2020-24455
Missing initialization of a variable in the TPM2 source may allow a privileged user to potentially enable an escalation of privilege via local access.
Does this matter?
Lower severity and a low EPSS score (0.58%). Track it; it rarely justifies an emergency change on its own.
Description
Missing initialization of a variable in the TPM2 source may allow a privileged user to potentially enable an escalation of privilege via local access. This affects tpm2-tss before 3.0.1 and before 2.4.3.
