Noroxi assessment

Priority: Monitor (action score 18/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.83% (FIRST EPSS); higher than 58.2% of all records.
  • Fixed version: linux-2.6.24 (Debian:4.0) 2.6.24-6~etchnhalf.6; kernel-rt (Red Hat:enterprise_mrg:1::el5) 0:2.6.24.7-81.el5rt; kernel-rt-debug (Red Hat:enterprise_mrg:1::el5) 0:2.6.24.7-81.el5rt.

Low priority for now. Upgrade to linux-2.6.24 (Debian:4.0) 2.6.24-6~etchnhalf.6; kernel-rt (Red Hat:enterprise_mrg:1::el5) 0:2.6.24.7-81.el5rt; kernel-rt-debug (Red Hat:enterprise_mrg:1::el5) 0:2.6.24.7-81.el5rt or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The sctp_getsockopt_hmac_ident function in net/sctp/socket.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, relies on an untrusted length value to limit copying of data from kernel memory, which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function.
