AI-suggested
A patch is available and has been released by Ubuntu for the affected kernel packages. Users should update their systems to the fixed versions listed in the advisory (e.g., 6.17.0-1012.12~24.04.1, 6.17.0-22.22~24.04.1, 6.17.0-1011.11~24.04.1, 6.17.0-1012.12, 6.17.0-1011.11) and reboot to apply the changes. Due to an ABI change, recompilation and reinstallation of third-party kernel modules may be required. Following the vendor's update instructions will mitigate these vulnerabilities.
Description
A vulnerability identified as EntrySign (CVE-2024-36347) affects some AMD Zen processors where CPU microcode signature verification is improperly performed. This flaw allows a privileged attacker to potentially load malicious CPU microcode, leading to loss of system integrity and confidentiality. Additionally, multiple other security issues were found and fixed in various Linux kernel subsystems. Updates addressing these vulnerabilities are available for linux-aws, linux-aws-6.17, linux-hwe-6.17, linux-oracle, and linux-oracle-6.17 kernels.
