Debian Bug : 1127597
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.
The Qualys Threat Research Unit (TRU) discovered several vulnerabilities
in Apparmor. Details can be found in the Qualys advisory at

For Debian 11 bullseye, these problems have been fixed in version

previous update. It additionally includes many more bug fixes from
