There is no upstream patch for this issue yet.

Comment 2 Carlos López 2021-12-20 10:29:21 UTC

Missed python2-numpy during my initial assessment.

The *-SP2 codestreams seem to be close to EOL, and since there is no upstream patch yet, they will probably not get an update, but I'm listing them for completeness.

Affected codestreams:
 - SUSE:SLE-15:Update
 - SUSE:SLE-15-SP2:Update

Also affected on openSUSE:
 - openSUSE:Backports:SLE-15-SP2
