Libtpms, which is derived from the TPM 2.0 reference implementation code published by the Trusted Computing Group, is prone to a potential out of bounds (OOB) read vulnerability. The vulnerability occurs in the \u2018CryptHmacSign\u2019 function with an inconsistent pairing of the signKey and signScheme parameters, where the signKey is ALG_KEYEDHASH key and inScheme is an ECC or RSA scheme. The reported vulnerability is in the \u2018CryptHmacSign\u2019 function, which is defined in the &#8220;Part 4: Supporting Routines \u2013 Code&#8221; document, section &#8220;7.151 &#8211; \/tpm\/src\/crypt\/CryptUtil.c &#8220;. This vulnerability can be triggered from user-mode applications by sending malicious commands to a TPM 2.0\/vTPM (swtpm) whose firmware is based on an affected TCG reference implementation. The effect on libtpms is that it will cause an abort due to the detection of the out-of-bounds access, thus for example making a vTPM (swtpm) unavailable to a VM. This vulnerability is fixed in 0.7.12, 0.8.10, 0.9.7, and 0.10.1.<br \/>\n<br \/>\n<strong>Severity:<\/strong> 5.9 | MEDIUM<br \/>\n<br \/>\nVisit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-49133 Published : June 10, 2025, 8:15 p.m. | 45\u00a0minutes ago Description : Libtpms is a library that targets the integration of TPM functionality into hypervisors, primarily into Qemu.
