In the Linux kernel, the following vulnerability has been resolved: nvme-fc: fix double free of fabrics options when nvme_add_ctrl() fails nvmf_create_ctrl() owns the fabrics options and frees them whenever ->create_ctrl() returns an error, so a transport must not free them on its own error paths. nvme-fc tracks this by testing ctrl->ctrl.opts in nvme_fc_ctrl_free(), which requires nvme_fc_init…

In the Linux kernel, the following vulnerability has been resolved: ALSA: harmony: initialize locks before requesting IRQ snd_harmony_create() registers the IRQ before initializing h->lock and h->mixer_lock. A pending interrupt can invoke the handler while these locks are uninitialized. Initialize both locks before requesting the IRQ so the handler always sees valid lock state.

Vulnerabilidad alta en Arista EOS OSPFv3: reinicio no autorizado de agente

Una vulnerabilidad en Arista EOS con OSPFv3 configurado (CVSS 7.5) permite que paquetes especialmente crafteados causen el reinicio inesperado del agente OSPFv3, interrumpiendo la disponibilidad de enrutadores en infraestructuras altas. El impacto afecta principalmente a operadores de redes en centros de datos y proveedores de conectividad en LATAM que dependen de equipos Arista para su backbone de red.

Vulnerabilidad alta en Arista EOS con OSPFv2 permite denegación de servicio en redes

Arista EOS es vulnerable a packets OSPFv2 especialmente diseñados que pueden ser enviados por atacantes no autenticados en el mismo segmento de broadcast. La vulnerabilidad provoca inestabilidad en adyacencias OSPF y pérdida de paquetes, disrumpiendo el enrutamiento en dominios OSPF amplios. En infraestructuras altas de LATAM (telecomunicaciones, finanzas, energía) esto compromete la disponibilidad de servicios de red.
