The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.

Security readout for executives and security teams

CVE-2008-2812 is an old Linux kernel flaw in tty-related networking drivers. A local user could crash the system and may be able to gain privileges. The business risk is highest for legacy Linux systems still running kernels before 2.6.25.10 or unpatched vendor equivalents. Exposure is limited to systems with local user access and vulnerable pre-2.6.25.10 Linux kernels or affected vendor builds. Modern supported distributions are unlikely to be exposed unless they run old, custom, embedded, or frozen kernels. Treat this as a legacy Linux hygiene issue with meaningful local-impact risk. It is not supported as internet-exploited by the supplied sources, but old multi-user systems should be remediated promptly because kernel crashes and possible privilege gain affect availability and trust boundaries. Mitigation focus: Upgrade to a vendor kernel containing the 2.6.25.10-era fix or later.; Review Debian, Ubuntu, SUSE, and Red Hat advisories for distribution-specific packages.; Prioritize legacy hosts allowing untrusted or multi-user shell access..
