CVE-2025-38393

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-38393
In the Linux kernel, the following vulnerability has been resolved: NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN We found a few different systems hung up in writeback waiting on the same page lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in pnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding count was zero. It seems most likely that this is another race between the waiter and waker similar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task"). Fix it up by applying the advised barrier.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: NFSv4/pNFS: Corrección de una ejecución para reactivar NFS_LAYOUT_DRAIN. Se encontraron varios sistemas bloqueados en espera de escritura diferida en el mismo bloqueo de página, y una tarea esperando el bit NFS_LAYOUT_DRAIN en pnfs_update_layout(). Sin embargo, el recuento plh_outstanding de pnfs_layout_hdr era cero. Lo más probable es que se trate de otra ejecución entre el que espera y el que reactiva, similar al commit ed0172af5d6f ("SUNRPC: Corrección de una ejecución para reactivar una tarea de sincronización"). Se soluciona aplicando la barrera recomendada.
