Medium 6.5CVE-2026-85769 Public exploit
Libtpms: libtpms: heap out-of-bounds read in tpm2 state unmarshalling via unchecked block_skip_read() blocksize
A flaw was found in libtpms, a library that provides software TPM 2.0 emulation. When restoring TPM 2.0 state (for example during a virtual machine's power-on or state/migration restore), a malformed state blob can supply an oversized skip-block length that i…

An information leakage vulnerability in the TCG TPM 2.0 reference code.
An information leakage vulnerability was reported in the TCG TPM 2.0 reference code that could allow a local attacker with elevated privileges to obtain a credential from a TPM-aware CA for a falsified TPM key (such as an Attestation Key, DevID Key or TLS aut…
