kernel/trace/ftrace.c in the Linux kernel before 2.6.35.5, when debugfs is enabled, does not properly handle interaction between mutex possession and llseek operations, which allows local users to cause a denial of service (NULL pointer dereference and outage of all function tracing files) via an lseek call on a file descriptor associated with the set_ftrace_filter file.

Security readout for executives and security teams

CVE-2010-3079 is an old Linux kernel denial-of-service issue. On vulnerable systems, a local user could trigger a crash or outage affecting function tracing files when debugfs is enabled. The provided sources do not show remote compromise, privilege escalation, or active exploitation. Exposure is mainly legacy Linux systems running kernels before 2.6.35.5 with debugfs enabled and local user access. Downstream Ubuntu, SUSE, and Red Hat advisories indicate distribution-packaged kernels may have been affected, but the bundle does not provide exact package lists. Treat this as a legacy platform hardening issue. It is not presented as remotely exploitable, but affected systems could suffer local denial of service. Prioritize remediation where old kernels support shared users, hosting environments, or production systems requiring kernel tracing stability. Mitigation focus: Update to Linux 2.6.35.5 or a vendor kernel containing the upstream fix.; Apply applicable Ubuntu, SUSE, or Red Hat security updates for affected legacy systems.; Disable or restrict debugfs where operationally feasible on legacy kernels..
