CVE-2008-4445

kernel: sctp: fix random memory dereference with SCTP_HMAC_IDENT option

Published Oct 6, 2008 CVSS 2.0 · 4.7 Medium EPSS < 1% KEV · Not listed
Description
The sctp_auth_ep_set_hmacs function in net/sctp/auth.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4, when the SCTP-AUTH extension is enabled, does not verify that the identifier index is within the bounds established by SCTP_AUTH_HMAC_ID_MAX, which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function, a different vulnerability than CVE-2008-4113.
