In the Linux kernel, the following vulnerability has been resolved:

sctp: validate Adaptation Indication parameter length

The Adaptation Layer Indication parameter contains a fixed 32-bit

Adaptation Code Point after its parameter header. However,

sctp_verify_param() accepts a header-only parameter because the generic

parameter walker only requires the header to be present.

sctp_process_param() then reads adaptation_ind beyond the declared

parameter. When the malformed parameter is last in an INIT, the read

starts at the receive skb tail, and the value is copied into the state

cookie returned in the INIT ACK. This may disclose four receive-buffer

tail bytes.

Require the declared parameter length to match the fixed structure size

and abort the association through the existing invalid parameter length

path otherwise. (NVD)
