CVE-2025-71268

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-71268
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix reservation leak in some error paths when inserting inline extent If we fail to allocate a path or join a transaction, we return from __cow_file_range_inline() without freeing the reserved qgroup data, resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data() in such cases.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: btrfs: corrige una fuga de reserva en algunas rutas de error al insertar una extensión en línea Si no logramos asignar una ruta o unirnos a una transacción, regresamos de __cow_file_range_inline() sin liberar los datos de qgroup reservados, lo que resulta en una fuga. Soluciona esto asegurando que llamamos a btrfs_qgroup_free_data() en tales casos.
