According to the mentioned CVE record the issue affects c-blosc2 v2.17.
The fix has been merged in in c-blosc2 v2.17.1 which is the version 
currently in testing.

My conclusion is the the current version of c-blosc2 in debian is OK so 
I will close this bug.
Please feel free to re-open if you do not agree.


kind regards
