CVE-2026-53225 (GCVE-0-2026-53225)

Vulnerability from cvelistv5 – Published: 2026-06-25 08:39 – Updated: 2026-08-05 12:34

Title

sctp: fix uninit-value in __sctp_rcv_asconf_lookup()

Summary

In the Linux kernel, the following vulnerability has been resolved: sctp: fix uninit-value in __sctp_rcv_asconf_lookup() __sctp_rcv_asconf_lookup() in net/sctp/input.c only checks that the ASCONF chunk can hold the ADDIP header and a parameter header, then calls af->from_addr_param(), which reads the full address (16 bytes for IPv6) trusting the parameter's declared length. An unauthenticated peer can send a truncated trailing ASCONF chunk that declares an IPv6 address parameter but stops after the 4-byte parameter header; reached from the no-association lookup path, from_addr_param() then reads uninitialized bytes past the parameter. Impact: an unauthenticated SCTP peer makes the receive path read up to 16 bytes of uninitialized memory past a truncated ASCONF address parameter. The sibling __sctp_rcv_init_lookup() bounds parameters with sctp_walk_params(); this path open-codes the fetch and omits the bound. Verify the whole address parameter lies within the chunk before from_addr_param() reads it, the same class of fix as commit 51e5ad549c43 ("net: sctp: fix KMSAN uninit-value in sctp_inq_pop").

There is no race or condition outside attacker control.\nPR:N - The association lookup path only checks that an AUTH chunk was seen before ASCONF; it does not validate the AUTH HMAC before the vulnerable read. The commit explicitly describes an unauthenticated peer reaching the bug.\nUI:N - No victim action is required after SCTP is reachable on the target. The attacker sends network packets directly to the kernel receive path.\nS:U - The vulnerability affects the kernel SCTP networking stack within the same operating-system security authority. It does not cross a VM, IOMMU, or sandbox boundary.\nC:H - The bug causes an unauthenticated out-of-bounds/uninitialized read of up to a full IPv6 address worth of bytes past a truncated ASCONF parameter. Under the provided guidance, this is scored High because it is an OOB read not strictly limited to a few harmless bytes.\nI:N - The vulnerable operation reads bytes into a temporary SCTP address used for lookup and does not write attacker data to kernel structures. No direct integrity modification or control-flow overwrite is present.\nA:H - The malformed packet can repeatedly trigger an invalid kernel receive-path read, and such out-of-bounds reads can fault or panic on hardened/sanitized deployments. With uncertainty resolved upward, availability impact is High."

Detection rules are retrieved from Rulezet.

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.
