The do_coredump function in fs/exec.c in the Linux kernel 2.6.19 sets the flag variable to O_EXCL but does not use it, which allows context-dependent attackers to modify arbitrary files via a rewrite attack during a core dump.

Security readout for executives and security teams

This is an old Linux kernel core-dump flaw. Under specific local conditions, an attacker could abuse how a crashed process writes its core file to rewrite files they should not control. The source bundle does not provide a CVSS score or confirmed active exploitation. Exposure is most plausible on legacy Linux systems or appliances based on Linux kernel 2.6.19 or vendor kernels carrying this code. Modern supported kernels are unlikely to be affected, but embedded or unsupported systems may remain exposed. Treat this as a legacy exposure issue. It is not listed as actively exploited, but arbitrary file modification in kernel core-dump handling can matter on shared or unsupported Linux systems. Mitigation focus: Identify systems running Linux kernel 2.6.19 or related vendor backports.; Apply the relevant kernel or vendor security update where available.; Review Red Hat, Trustix, Avaya, and kernel guidance for affected packages..
