Fellow Linux admins-

Kernel vulnerabilities can often lead to serious system compromise, so it's obviously crucial to update as soon as the fixes are made available. Linux 6.13-rc4 includes a crucial security fix targeting speculative execution vulnerabilities in virtual environments. These vulnerabilities are important for admins managing virtual environments, as they can allow unauthorized access to sensitive data across virtual machines.

Read on to learn more about this update, along with USB bug fixes for better system reliability and an update to the Enhanced Read-Only File System (EROFS), which significantly improves container start-up times.

You'll also learn about the recent discovery that Qualcomm Snapdragon X Plus and Elite processors are still vulnerable to Spectre-related attacks.
