CVE-2005-3273: The rose_rt_ioctl function in rose_route.c for Radionet Open Source Environment (ROSE) in Linux 2.6 kernels...

Security readout for executives and security teams

This is an old Linux kernel flaw in the ROSE amateur-radio networking route code. A malformed route request with too many digipeats could trigger out-of-bounds array behavior. Business urgency depends on whether any legacy Linux 2.4 or early 2.6 systems still exist and use ROSE/AX.25 networking. Likely exposure is limited to legacy Linux systems running affected 2.4 or early 2.6 kernels, especially where ROSE networking support is present or operational. Modern supported distributions are unlikely to be affected, but embedded, appliance, lab, or long-lived industrial systems should be checked. Treat this as a legacy exposure cleanup item, not an internet-wide emergency based on the supplied evidence. Escalate if affected kernels remain in production, especially on specialized systems that are hard to patch or poorly inventoried. Mitigation focus: Upgrade Linux 2.6 kernels to 2.6.12 or later where applicable.; Upgrade Linux 2.4 kernels to 2.4.29 or later where applicable.; Apply relevant Debian, Ubuntu, Red Hat, or Mandriva kernel advisories..
