A patch is available and included in updated kernel versions 5.15.0-1116.123~20.04.1, 5.15.0-1122.131~20.04.1, 5.15.0-1121.130~20.04.1, and 5.15.0-1111.117~20.04.1. Users should update their systems to these versions or later and reboot to apply the fixes. Due to ABI changes, recompilation and reinstallation of third-party kernel modules are required. Ubuntu Pro subscribers have access to these fixes. No known exploits are reported in the wild at this time.
Description
Multiple security vulnerabilities were discovered in the Linux kernel versions used in AWS, Azure, and Intel IoT platforms, including a critical flaw in ARM64 processors where a local attacker could write to memory after permissions were revoked, potentially bypassing memory protections or escalating privileges. These issues affect various subsystems such as network drivers, file systems, and protocols. Fixes are available in updated kernel versions, and users are advised to apply these updates and reboot their systems.
