TL;DR: Debian published DSA-6602-1, a security update for the linux package. The announcement gives no further details here, so read the Debian security tracker for the CVEs and fixed versions.
What happened
The Debian Security Advisories feed published DSA-6602-1 on November 2, 2026, a security update for linux. The Debian security tracker page for the advisory lists the CVEs and the fixed package version for each release, so use it for exact numbers. We quote no severity because the announcement gives none.
Am I affected?
Any Debian server with the linux package installed is in scope until it takes the update. To check one machine by hand, run dpkg -l linux to see the installed version, then apt update followed by apt install --only-upgrade linux. Debian backports fixes, so the version may look old after the update, which is why you compare against the tracker rather than the upstream release.
How to check with Stackurity
Stackurity's read-only agent reads installed packages on Debian servers and matches them against advisories every hour, using Debian's own version rules so that backports are not reported as false alarms. It shows the upgrade to move to, and check again records whether the issue is really gone. See how fixes are tracked in the docs.
