The big brains at Qualys will keep you protected.
Users should update Ubuntu 24.04 and 23.10 to secure their systems. The Qualys Threat Research Unit (TRU) recently disclosed three security bypasses in Ubuntu’s unprivileged user namespace restrictions. Qualys responsibly disclosed these vulnerabilities to the Ubuntu Security Team on 15th January.
