Summary
padata: use integer wrap around to prevent deadlock on seq_nr overflow
Details

In the Linux kernel, the following vulnerability has been resolved:

padata: use integer wrap around to prevent deadlock on seq_nr overflow

When submitting more than 2^32 padata objects to padatadoserial, the current sorting implementation incorrectly sorts padata objects with overflowed seqnr, causing them to be placed before existing objects in the reorder list. This leads to a deadlock in the serialization process as padatafindnext cannot match padata->seqnr and pd->processed because the padata instance with overflowed seq_nr will be selected next.

To fix this, we use an unsigned integer wrap around to correctly sort padata objects in scenarios with integer overflow.
