A flaw was found in GnuPG. This vulnerability, a stack-based buffer overflow, occurs in the `tpm2daemon` component when processing PKDECRYPT commands for cryptographic keys secured by a Trusted Platform Module (TPM). A local attacker could exploit this to execute unauthorized code, potentially gaining full control of the system, or disrupt its operation, leading to a denial of service.
