Comment 1 Alexander Bergmann 2023-04-04 05:44:58 UTC 
Only 15-SP5 and Factory are affected. The 15-SP3 code stream does not have the affected code path.

SUSE:SLE-15-SP3:Update  libyang-1.0.184
SUSE:SLE-15-SP5:GA      libyang-2.0.231
openSUSE:Factory        libyang-2.1.30

Thanks for the report,
Commit that fix this issue: https://github.com/CESNET/libyang/commit/dc668d296f9f05aeab6315d44cff3208641e3096

I am going to update libyang on Factory from 2.1.30 to 2.1.55 where the commit is pushed, and add a patch for 15-SP5.
