CVE-2013-6378: The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through 3.12....

Security readout for executives and security teams

CVE-2013-6378 is a Linux kernel denial-of-service flaw in the Libertas wireless debugfs handling. A local user with root privileges could trigger a kernel OOPS using a zero-length write. The practical business risk is limited because exploitation requires root-level local access, but legacy systems may still need patch verification. Exposure is most likely on older Linux systems running kernels through 3.12.1, or vendor kernels covered by the cited 2014 advisories, where the Libertas wireless driver and debugfs path are present. The source data does not provide precise affected package versions. Treat this as low urgency unless legacy Linux hosts remain in production or root-level operational stability is business-critical. Patch through normal kernel maintenance, with priority for unsupported or appliance-like systems that are difficult to monitor or reboot safely. Mitigation focus: Apply the relevant vendor kernel security update for the affected distribution.; Confirm the running kernel includes upstream commit a497e47d4aec37aaf8f13509f3ef3d1f6a717d88 or a backport.; Retire or isolate unsupported systems running Linux kernels through 3.12.1..
