An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before 1.15.2.
Noroxi assessment
Priority: Monitor (action score 26/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 65.4% of all records.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: dbus (AlmaLinux:8) 1:1.12.8-23.el8_7.1; dbus-common (AlmaLinux:8) 1:1.12.8-23.el8_7.1; dbus-daemon (AlmaLinux:8) 1:1.12.8-23.el8_7.1.
Low priority for now. Upgrade to dbus (AlmaLinux:8) 1:1.12.8-23.el8_7.1; dbus-common (AlmaLinux:8) 1:1.12.8-23.el8_7.1; dbus-daemon (AlmaLinux:8) 1:1.12.8-23.el8_7.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before 1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash when receiving a message with certain invalid type signatures.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
