Comment 5 John Helmert III 2022-03-19 05:10:12 UTC 
The Github advisory referenced by the CVE (https://github.com/bluez/bluez/security/advisories/GHSA-479m-xcq5-9g2q) seems to claim this vulnerability can result in remote code execution, but the CVE says the impact is only denial of service. Why the discrepancy?

Also, for the benefit of downstreams, can a reference to the patch be added to the CVE?
