DoS in Linux kernel SCTP sctp_process_unk_param via crafted SCTPChunkInit

IdentifiersCVE-2010-1173CWE-400

CVE-2010-1173 is a denial-of-service vulnerability in the Linux kernel’s SCTP implementation. In Linux kernel 2.6.33.3 and earlier, when SCTP support is enabled, the function sctp_process_unk_param (net/sctp/sm_make_chunk.c) can be triggered by a remote attacker sending an SCTPChunkInit packet containing multiple invalid parameters. Processing these invalid parameters causes the kernel to generate/accumulate an excessively large amount of error data, leading to resource exhaustion and a system crash.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A remote, unauthenticated attacker can cause a denial of service by crashing the target system (kernel crash) over the network via crafted SCTP traffic when SCTP is enabled. This results in loss of availability and may require a reboot to recover.

Mitigation

If you can’t patch tonight, do this now.

If patching is not immediately possible, reduce exposure by disabling SCTP support (e.g., unload/blacklist the sctp module where feasible) and/or filtering SCTP at network boundaries/host firewalls to prevent untrusted SCTP traffic from reaching the host.

Remediation

Patch, then assume compromise.

Upgrade to a Linux kernel version that includes the upstream fix for CVE-2010-1173 (i.e., a version newer than 2.6.33.3 with the relevant SCTP error-handling correction), or apply the vendor-provided patched kernel for the affected distribution/kernel line.
