Title
padata: use integer wrap around to prevent deadlock on seq_nr overflow
Summary
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 padata_do_serial, the
current sorting implementation incorrectly sorts padata objects with
overflowed seq_nr, causing them to be placed before existing objects in
the reorder list. This leads to a deadlock in the serialization process
as padata_find_next cannot match padata->seq_nr 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.

Esto conduce a un bloqueo en el proceso de serializaci\u00f3n ya que padata_find_next no puede coincidir con padata-\u0026gt;seq_nr y pd-\u0026gt;processed porque la instancia de padata con seq_nr desbordado se seleccionar\u00e1 a continuaci\u00f3n.

"value": "AV:N - The seq_nr counter is driven by ESP packet processing \u2014 `xfrm_input()` reaches `esp_input` \u2192 `crypto_aead_decrypt` \u2192 pcrypt \u2192 `padata_do_parallel` for every inbound ESP packet, and outbound tunnel traffic burns counters on the encrypt shell, so a remote attacker on an IPsec gateway using pcrypt can drive the 32-bit counter to overflow purely with network traffic.\nAC:L - The attacker needs only to sustain packet/request volume until the 32-bit counter wraps \u2014 entirely under their control, with no race window, no memory-layout dependency, and no unknown target state.\nPR:N - The `padata_do_parallel` call happens before ICV/authentication verification in `xfrm_input()`, so forged ESP packets from an unauthenticated attacker consume sequence numbers; outbound-direction counter consumption requires no credentials or SPI knowledge whatsoever.\nUI:N - The counter advances automatically as the kernel processes attacker-supplied traffic; no victim action of any kind is needed.\nS:U - The stalled reorder list and leaked objects are confined to the kernel\u0027s own crypto pipeline; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an ordering/comparison error in list insertion \u2014 nothing is read out of bounds and no kernel memory contents are exposed to the attacker.\nI:N - The mis-sort causes `padata_find_next()` to refuse to dequeue rather than to deliver objects out of order, so no data is modified or corrupted and no control-flow primitive is created.\nA:H - The reorder list deadlocks permanently, hanging every subsequent request through that pcrypt algorithm system-wide (the shell is per-instance, shared by all tfms), leaking each queued skb/request and the `parallel_data` forever \u2014 an irrecoverable IPsec/crypto outage plus unbounded memory exhaustion until reboot."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
