Notes
- mbedtls <not-affected> (Vulnerable code not enabled in any build which supports TLS 1.3)

https://github.com/Mbed-TLS/mbedtls/commit/ad736991bb59211118a29fe115367c24495300c2 (mbedtls-3.6.0)
Experimental TLS 1.3 support not enabled in 2.x packages, TLS 1.3 is enabled
in Debian/experimental, but the first upload directly provides fixes, so mark
as <not-affected> altogether
