Filed under
Security

The new Ubuntu Linux kernel security update is available for the Ubuntu 21.04 (Hirsute Hippo), Ubuntu 20.04 LTS (Focal Fossa), and Ubuntu 18.04 LTS (Bionic Beaver) operating system series, and addresses three security issues related to the Bluetooth subsystem and NFC implementation and affecting all three releases.

These are CVE-2021-3564 and CVE-2021-3573, two flaws discovered in Linux kernel’s Bluetooth subsystem that could lead to a double-free vulnerability or a use-after-free vulnerability, respectively, allowing an attacker to cause a denial of service or possibly execute arbitrary code.

17.5 Years!

Tux Machines started in 2004. We're soon entering 2022.

AS we noted about a month ago, today is a very special day because it's a decimally-significant (quarter decade times seven) anniversary for us as we approach our 160,000th site node. Meaningful milestones are rare; they're superficial, but they help morale.

Tux Machines microwaveThanks to all those who regularly contribute stories (Marius, Arindam etc.) and to readers who have been gathering news about GNU/Linux through Tux Machines for as long as we've existed. Since our last server reboot we've served 115 million hits. Since the birth of the site it certainly adds up to several billions. Maybe we'll have over 200,000 nodes some time before our 20-year anniversary. Time will tell...
