CVE-2026-45941

CVE-2026-45941 concerns the Linux kernel tpm_i2c_infineon locality handling. The root cause is a timeout in get_burstcount() that can return -EBUSY and cause the function to exit without releasing the locality acquired earlier in tpm_tis_i2c_send(), risking resource exhaustion. The mitigation acr...

CVE-2026-45871 tpm: st33zp24: Fix missing cleanup on get_burstcount() error

In the Linux kernel, the following vulnerability has been resolved: tpm: st33zp24: Fix missing cleanup on getburstcount error getburstcount can return -EBUSY on timeout. When this happens, st33zp24send returns directly without releasing the locality acquired earlier. Use goto outerr to ensure...

CVE-2026-45871

CVE-2026-45871 affects the Linux kernel TPM subsystem (st33zp24 driver). A failure in get_burstcount() can return -EBUSY on timeout, causing st33zp24_send() to exit without releasing the previously acquired locality, risking resource exhaustion and local DoS by making the TPM device unavailable. ...

SUSE CVE-2023-43635

Vault Key Sealed With SHA1 PCRs The measured boot solution implemented in EVE OS leans on a PCR locking mechanism. Different parts of the system update different PCR values in the TPM, resulting in a unique value for each PCR entry. These PCRs are then used in order to seal/unseal a key from the...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in the Linux kernel’s implementation of proxied virtualized TPM devices. In a system where virtualized TPM devices are enabled which is not the default setting, a local attacker can exploit this flaw to create a “use-after-free” condition, potentially allowing them to escala...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: tpm: In tpmcrb, add acpiputtable to fix a memory leak. In crbacpiadd, we obtain the TPM2 table to retrieve information such as the start method, and then assign those values to private data. Therefore, the TPM2 table is not used...

Zero-Day Exploit Against Windows BitLocker

It's nasty, but it requires physical access to the computer: The exploit, named YellowKey, was published earlier this week by a researcher who goes by the alias Nightmare-Eclipse. It reliably bypasses default Windows 11 deployments of BitLocker, the full-volume encryption protection Microsoft...
