Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A size validation fix is required in the
sctp sf ootb() function to address a crash reported by syzbot. The issue is related to the sctp protocol and involves a failure to properly validate chunk size, which can lead to a crash. The crash is reported with the error message BUG: KMSAN: uninit-value in sctp sf ootb+0x7f5/0xce0 net/sctp/sm statefuns.c:3712. The issue is addressed by adding size validation when walking chunks, similar to the fix in Commit 50619dbf8db7.Recommendations:
As a temporary workaround, consider disabling the
sctp protocol until a patch is available. Restrict access to the sctp sf ootb() function to minimize the risk of exploitation. Avoid using the sctp protocol in sensitive environments until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
