HIGHCVSS 2.0
EPSS 2.02%
Description
The sctp_auth_asoc_get_hmac function in net/sctp/auth.c in the Linux kernel before 2.6.36 does not properly validate the hmac_ids array of an SCTP peer, which allows remote attackers to cause a denial of service (memory corruption and panic) via a crafted value in the last element of this array.
