The rose_parse_ccitt function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 does not validate the FAC_CCITT_DEST_NSAP and FAC_CCITT_SRC_NSAP fields, which allows remote attackers to (1) cause a denial of service (integer underflow, heap memory corruption, and panic) via a small length value in data sent to a ROSE socket, or (2) conduct stack-based buffer overflow attacks via a large length value in data sent to a ROSE socket.

Security readout for executives and security teams

This is an old Linux kernel ROSE networking flaw. A remote attacker could send malformed data to a ROSE socket and crash the system, and the CVE also describes possible stack-based buffer overflow behavior. The bundle does not provide CVSS scoring or evidence of active exploitation. Exposure is most plausible on systems running Linux kernels before 2.6.39, or vendor kernels lacking the referenced backport, where ROSE networking support is present and reachable. Modern supported distributions are less likely exposed, but legacy embedded, appliance, or long-lived systems need verification. Treat as a legacy-kernel exposure issue. It is not KEV-listed in the bundle, but affected systems could be remotely crashed and may face memory-corruption risk. Focus on confirming whether old Linux kernels still exist in production or embedded environments. Mitigation focus: Upgrade to Linux kernel 2.6.39 or a vendor-supported fixed backport.; Confirm vendor advisories for distribution-specific package names and fixed versions.; Prioritize legacy systems that expose or depend on ROSE networking..
