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

sctp: properly validate chunk size in sctp_sf_ootb()

A size validation fix similar to that in Commit 50619dbf8db7 ("sctp: add size validation when walking chunks") is also required in sctp_sf_ootb() to address a crash reported by syzbot:
