Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: tpm: fixed reference counting for struct tpmchip The following sequence of operations results in a refcount warning: 1. Open the device /dev/tpmrm. 2. Remove the module tpmtisspi. 3. Write a TPM command to the file descriptor...

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...

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 – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: tpm: Clean up the TPM space after a command failure. tpmdevtransmit prepares the TPM space before attempting command transmission. However, if the command fails, no rollback of this preparation occurs. This can lead to transient...
