BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and invalid capabilities can be processed in profiles/audio/avdtp.c.

Security readout for executives and security teams

Plain-English summary

This affects BlueZ, the Bluetooth stack used on many Linux systems. A nearby attacker could send malformed Bluetooth audio capability data and disrupt service. The source bundle supports physical proximity and denial-of-service risk, not internet-scale remote exploitation.

Executive priority

Treat as a high-priority hygiene issue for Bluetooth-enabled Linux assets, especially devices in public or shared physical environments. Business urgency is lower than internet-exposed RCE because proximity is required.

Technical view

BlueZ before 5.59 can mishandle malformed or invalid AVDTP capabilities in profiles/audio/avdtp.c. The supplied CVSS is 8.8, but the description names denial of service; the bundle does not explain the broader confidentiality or integrity scoring.

Likely exposure

Linux endpoints, servers, embedded devices, or appliances using vulnerable BlueZ packages are plausible exposure points when Bluetooth is enabled and reachable by nearby attackers.

Exploitation context

CISA KEV is false, and the bundle provides no evidence of active exploitation. The attacker must be physically proximate or otherwise within Bluetooth adjacency.

Researcher notes

Focus validation on BlueZ AVDTP handling and distro backports. Avoid assuming affected products beyond BlueZ and vendors cited in the bundle. The severity description and CVSS impact fields appear broader than the stated DoS condition.

Mitigation direction

  • Apply vendor BlueZ security updates from Ubuntu, Debian, NetApp, or relevant distribution guidance.
  • Confirm systems are no longer running BlueZ versions earlier than 5.59, accounting for vendor backports.
  • Disable Bluetooth on systems where it is not operationally required.
  • Prioritize exposed workstations, kiosks, embedded devices, and appliances in public or shared spaces.

Validation and detection

  • Inventory systems and appliances that include BlueZ or Bluetooth services.
  • Check installed BlueZ package versions against vendor security advisories.
  • Verify Bluetooth is disabled where not required.
  • Review system logs for repeated Bluetooth or audio profile crashes.
  • Track vendor advisories for backported package names and fixed versions.
