I am okay to merge this PR as the security issue.
But waiting for @ned-deily and @ericvsmith 's comment :)

As I commented on the bpo issue, please add the CVE to the NEWS item. |
…terface (pythonGH-21033) The __hash__() methods of classes IPv4Interface and IPv6Interface had issue of generating constant hash values of 32 and 128 respectively causing hash collisions. The fix uses the hash() function to generate hash values for the objects instead of XOR operation (cherry picked from commit b30ee26) Co-authored-by: Ravi Teja P <rvteja92@gmail.com> Signed-off-by: Tapas Kundu <tkundu@vmware.com>
