Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_pipapo_avx2: don't
return non-matching entry on expiry New test case fails unexpectedly when avx2 matching functions are
used. The test first loads a ranomly generated pipapo set with 'ipv4 . port' key, i.e. nft -f foo. This
works. Then, it reloads the set after a flush: (echo flush set t s; cat foo) | nft -f - This is expected
to work, because its the same set after all and it was already loaded once. But with avx2, this fails: nft
reports a clashing element. The reported clash is of following form: We successfully re-inserted a . b c .
d Then we try to insert a . d avx2 finds the already existing a . d, which (due to 'flush set') is marked
as invalid in the new generation. It skips the element and moves to next. Due to incorrect masking, the
skip-step finds the next matching element *only considering the first field*, i.e. we return the already
reinserted "a . b", even though the last field is different and the entry should not have been matched. No
such error is reported for the generic c implementation (no avx2) or when the last field has to use the
'nft_pipapo_avx2_lookup_slow' fallback. Bisection points to 7711f4bb4b36 ("netfilter: nft_set_pipapo: fix
range overlap detection") but that fix merely uncovers this bug. Before this commit, the wrong element is
returned, but erronously reported as a full, identical duplicate. The root-cause is too early return in
the avx2 match functions. When we process the last field, we should continue to process data until the
entire input size has been consumed to make sure no stale bits remain in the map. (CVE-2026-43114)
