The IPv6 flow label handling code (ip6_flowlabel.c) in Linux kernels 2.4 up to 2.4.32 and 2.6 before 2.6.14 modifies the wrong variable in certain circumstances, which allows local users to corrupt kernel memory or cause a denial of service (crash) by triggering a free of non-allocated memory.

Security readout for executives and security teams

CVE-2005-3806 is an old Linux kernel flaw in IPv6 flow-label handling. A local user on an affected host could crash the system or corrupt kernel memory. The business risk is mainly to legacy Linux systems that still run kernels in the affected 2.4 or early 2.6 ranges. Exposure is most likely on unmanaged, embedded, or legacy Linux hosts with affected kernels and local user access. Modern supported Linux distributions should generally be unaffected if vendor kernel updates were applied. Treat as a legacy-system hygiene issue, not an internet-wide emergency. Prioritize remediation where affected kernels still support shared users, hosting workloads, or critical services that cannot tolerate crashes. Mitigation focus: Identify systems running affected Linux 2.4 or early 2.6 kernels.; Apply vendor kernel updates from the relevant distribution advisory.; Migrate unsupported legacy kernels to supported Linux releases..
