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.
