Several vulnerabilities have been discovered in the Linux kernel that could lead to privilege escalation, denial of service, or information disclosure.

Many apparmor related issues were fixed. This update also fixes a regression that caused GRE6 tunnels to stop working due to a decapsulation failure (Debian bug #1127597).



For Debian 10 buster, these problems have been fixed in version 6.1.164+1~deb10u1.

For Debian 9 stretch, these problems have been fixed in version 6.1.164+1~deb9u1.

We recommend that you upgrade your linux-6.1 packages.
