CVE-2012-5532: The main function in tools/hv/hv_kvp_daemon.c in hypervkvpd, as distributed in the Linux kernel before 3.8-...

Security readout for executives and security teams

CVE-2012-5532 is a local denial-of-service issue in Linux Hyper-V KVP daemon handling. A local user could crash the daemon, potentially disrupting guest-to-host key-value exchange integration on affected Hyper-V Linux guests. The sources do not indicate remote compromise or active exploitation. Exposure is most relevant to Linux systems running as Hyper-V guests with hypervkvpd from kernels before 3.8-rc1 or unfixed vendor packages. The provided affected-product data is incomplete. Treat as a targeted maintenance item, not an emergency. Patch affected Hyper-V Linux guests during normal vulnerability remediation, with higher priority where untrusted local users exist. Mitigation focus: Apply vendor kernel or hypervkvpd updates that include the upstream fix.; Prioritize Hyper-V Linux guests running kernels before 3.8-rc1.; Use Red Hat, Mandriva, or distribution advisories to identify fixed package versions..
