CVE-2015-1421 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 9.90% chance of exploitation in the next 30 days.
