AI-suggested
A patch is available in Linux kernel version 6.8.0-1040.44. Users should update their systems to this version and reboot to apply the fixes. Due to an ABI change, recompilation and reinstallation of any third-party kernel modules are necessary after the update. Following the vendor's update instructions will mitigate the vulnerabilities.
Description
Multiple security vulnerabilities were discovered in the Linux kernel for Raspberry Pi systems affecting several subsystems including Ext4 file system, packet sockets, network traffic control, TLS protocol, VMware vSockets driver, and XFRM subsystem. These flaws could potentially allow an attacker to compromise the system. A fixed kernel version 6.8.0-1040.44 has been released to address these issues. Users are advised to update and reboot their systems. Due to an ABI change, third-party kernel modules may need recompilation.
