The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option.

Security readout for executives and security teams

CVE-2012-6704 is a Linux kernel flaw that can let a local actor with CAP_NET_ADMIN crash the system. The available sources describe denial of service from memory corruption and only suggest other impact as unspecified, so business risk is mainly service disruption on old kernels. Exposure is most likely on legacy Linux systems running kernels before 3.5, or vendor kernels missing the referenced upstream fix. Risk increases where untrusted local users, services, or containers can obtain CAP_NET_ADMIN. Prioritize remediation on legacy or multi-tenant Linux hosts where local users or containers may have elevated network administration capability. For modern patched fleets, urgency is lower but should be verified. Mitigation focus: Identify Linux systems running kernels before 3.5 or vendor backports lacking the fix.; Apply vendor-supported kernel updates that include the referenced upstream correction.; Restrict CAP_NET_ADMIN to trusted users, services, and containers only..
