Debian 11 (“Bullseye”): Security update closes vulnerabilities in the LTS kernel

The Debian project has closed numerous vulnerabilities in the operating system kernel Linux 5.10 LTS from Debian 11 (“Bullseye”) with a massive security update. A total of 19 security vulnerabilities, some of which were serious, which could lead to an escalation of rights, among other things, have been fixed.

In addition to the escalation of rights, the so-called privilege escalation, some of the vulnerabilities in the LTS -Kernel also provokes a refusal of service, i.e. a Denial of Service (DoS) and information leaks as well as local attacks on the system.

Major update closes numerous gaps

The total of 19 vulnerabilities were in the areas of the subsystem for the Netfilter, the sound subsystem for PCM sound hardware and the implementation of KVM for x86 processors.

Below are all the vulnerabilities in Debian GNU/Linux 11 that were fixed with the help of the security update.

All security vulnerabilities are now fixed with the update to the latest LTS kernel Linux 5.10.113-1, which is why an update is recommended for every user running this operating system kernel.

Update and restart required

The update is performed using sudo apt update && sudo apt full-upgrade initiated via the console and is successfully completed after a reboot.

The new kernel is also available for download for other free operating systems that use Linux 5.10 LTS, and the XanMod Linux kernel has also been updated accordingly.

The source code and the patch and the PGP signature for Linux 5.10.113 can also be downloaded or viewed.
