CVE-2015-1421
HighSummary
A use-after-free vulnerability in the sctp_assoc_update function in the Linux kernel before version 3.18.8 allows remote attackers to cause a denial of service through memory corruption and system panic. It may also lead to unspecified other impacts due to an INIT collision that results in improper handling of shared-key data.
Risk Assessment
Organizations may be exposed to remote attacks that can lead to system crashes and potential other unforeseen consequences. This can affect service availability and system stability.
Recommendation
It is recommended to update the Linux kernel to version 3.18.8 or later to mitigate this vulnerability. Additionally, monitoring systems for unusual behavior may help in detecting attempted attacks.

Original NVD description (English source)
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.
