CVE-2007-3848: Linux kernel 2.4.35 and other versions allows local users to send arbitrary signals to a child process that...

Security readout for executives and security teams

This is an old Linux kernel flaw where a local user could influence a signal sent to a more privileged child process after a setuid-root parent process exits. It is not described as remotely exploitable, and the source bundle does not show active exploitation. Exposure is most likely on legacy Linux systems running affected 2.4-era kernels or distribution kernels covered by the listed 2007-2008 vendor advisories. Modern managed Linux fleets are less likely exposed, but legacy appliances and unsupported servers need checking. Treat as a legacy-platform risk, not an internet-edge emergency. Prioritize asset discovery and patch confirmation for old Linux servers, appliances, or environments with shared local user access. Mitigation focus: Inventory Linux kernel versions, especially legacy 2.4.x systems.; Review applicable Red Hat, SUSE, Ubuntu, and distribution advisories.; Apply vendor-supported kernel updates where available..
