What to check
- Applies to
- The 5 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
ANSSI (CERT-FR) published an advisory covering multiple vulnerabilities discovered in the Linux kernel as packaged for Debian trixie, affecting versions prior to 2.41.5-0+deb13u1. The flaws allow an attacker with local access to escalate privileges on affected systems. No indication of active exploitation is provided in the advisory.
Five CVEs are referenced (CVE-2026-13595, CVE-2026-27456, CVE-2026-53612, CVE-2026-53613, CVE-2026-53614). Debian has released a security update (DSA msg00353, 14 August 2026) addressing these issues. Administrators running Debian trixie should apply the updated kernel package as soon as possible to remediate the privilege escalation risk.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
