New submission from Christian Heimes:

Similar to #24011 and #24010 the pyexpat module's init function fails to check some return values for NULL. The patch doesn't include proper reference cleanups as most of the other parts of PyInit_pyexpat() don't cleanup on error, too.

CID 982779 (#2 of 2): Dereference null return value (NULL_RETURNS)
dereference: Dereferencing a pointer that might be null sys_modules when calling PyDict_SetItem

CID 982240 (#2 of 2): Unchecked return value (CHECKED_RETURN)
check_return: Calling PyDict_SetItem without checking return value (as is done elsewhere 158 out of 174 times)
