In the Linux kernel, the following vulnerability has been resolved: scsi: bsg: Fix TOCTOU in io_uring passthrough command setup scsi_bsg_uring_cmd() reads bsg_uring_cmd from the shared mmap'd SQE. Userspace can change a field after we check it and before we use it. request_len is the sharp case: it can grow past sizeof(scmd->cmnd) after the bound check and overflow scmd->cmnd in copy_from_user()…

In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: check the data direction of a C2HData PDU nvme_tcp_handle_c2h_data() finds the request by command id and checks that it has a payload, but it does not check that the command asked for data to be read. A controller that answers a write command with C2HData therefore reaches nvme_tcp_recv_data(), where _copy_to_iter() h…

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 con gNSI permite escalada de privilegios (CVE-2026-73454)

Plataformas Arista EOS con interfaz gRPC Network Security Interface (gNSI) Credentialz configurada son vulnerables a solicitudes especialmente diseñadas que modifican propiedades de cuentas de usuario. Un atacante podría asignar privilegios elevados a cuentas existentes, comprometiendo el control de acceso en infraestructura de red alta. El impacto afecta directamente a proveedores de servicios y centros de datos en LATAM que dependen de equipos Arista para segmentación y control de tráfico.
