CVE-2013-4514: Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow loc...

Security readout for executives and security teams

This is an old Linux kernel flaw in a staging wireless driver. A local user or process with CAP_NET_ADMIN could trigger buffer overflows using an overly long station name, causing denial of service or possibly other undefined impact. The practical risk depends on whether the vulnerable driver exists and whether privileged network capabilities are exposed. Exposure is most plausible on legacy Linux systems running kernels before 3.12, or vendor kernels missing the relevant backport, with the wlags49_h2 staging wireless driver built or loaded. Systems without that driver or without local CAP_NET_ADMIN exposure are less likely to be affected. Treat this as a legacy Linux hygiene issue unless affected kernels and the staging driver are present. Prioritize internet-facing or multi-tenant systems only if local users or workloads can obtain CAP_NET_ADMIN. The main documented business impact is service disruption. Mitigation focus: Upgrade to a kernel or vendor package containing the Linux 3.12 fix or backport.; Apply relevant Ubuntu or openSUSE kernel advisories where those distributions are in use.; Disable or remove the wlags49_h2 staging driver if it is not operationally required..
