What to check
- Applies to
- The 40 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.
CERT-FR has published an advisory summarizing a large batch of vulnerabilities affecting Microsoft Azure Linux (azl3) distribution packages, including clamav, curl, erlang, glib, keras, libXfont2, mtr, nodejs, openssh, perl-DBI, python-msgpack, python-setuptools, telegraf, vim, and xorg-x11-server-Xwayland. Each affected package has a specific version threshold below which systems are considered vulnerable, with fixed versions available from Microsoft.
The advisory does not specify the exact nature of the security impact for each CVE, stating only that a successful attacker could trigger an unspecified security issue. Roughly 40 CVEs are referenced across the affected components, spanning issue disclosure dates from late June through mid-July 2026. This is a standard vendor patch bulletin aggregation rather than a report of active exploitation, targeted campaign, or novel technique.
Organizations running Microsoft Azure Linux 3.0 (azl3) should prioritize patching per the referenced Microsoft Security Response Center bulletins for each CVE. No indicators of compromise, threat actor attribution, or malware association are present in this disclosure; the advisory is purely a consolidated notification of upstream package updates.

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 16,445 reports from 149 sources, 666 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.
