Description Eugene Teo (Security Response) 2008-10-06 06:05:14 UTC
Description of problem:
Wei Yongjun reported that "Since call to function sctp_sf_abort_violation() need paramter 'arg' with 'struct sctp_chunk' type, it will read the chunk type and chunk length from the chunk_hdr member of chunk. But call to sctp_sf_violation_paramlen() always with 'struct sctp_paramhdr' type's parameter, it will be passed to sctp_sf_abort_violation(). This may cause kernel panic.

   sctp_sf_violation_paramlen()
     |-- sctp_sf_abort_violation()
        |-- sctp_make_abort_violation()

This patch fixed this problem. This patch also fix two place which called sctp_sf_violation_paramlen() with wrong paramter type."
