Summary
Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel before 3.18.8 allows remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
