A typo in Linux kernel 2.6 before 2.6.21-rc6 and 2.4 before 2.4.35 causes RTA_MAX to be used as an array size instead of RTN_MAX, which leads to an "out of bound access" by the (1) dn_fib_props (dn_fib.c, DECNet) and (2) fib_props (fib_semantics.c, IPv4) functions.

Security readout for executives and security teams

This is an old Linux kernel bug caused by a typo in route-related array sizing. It could allow out-of-bounds memory access in IPv4 and DECNet kernel code. The bundle does not provide CVSS, confirmed impact beyond the bug class, or evidence of active exploitation. Exposure is mainly legacy Linux systems still running affected 2.4 or 2.6 kernel lines, or old distribution kernels covered by the listed vendor advisories. Modern supported Linux distributions are unlikely to be affected unless carrying obsolete kernels. Treat as a legacy exposure cleanup item unless affected old kernels are still present. The business risk is concentrated in unsupported Linux assets, where missing kernel maintenance may indicate broader operational risk. Mitigation focus: Identify hosts running Linux 2.4 or early 2.6 kernels.; Apply kernel updates from the relevant Linux distributor advisory.; Move upstream kernels to 2.6.21-rc6, 2.4.35, or later..
