      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5e: kTLS, Fix incorrect page refcounting\n\nThe kTLS tx handling code is using a mix of get_page() and\npage_ref_inc() APIs to increment the page reference. But on the release\npath (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.\n\nThis is an issue when using pages from large folios: the get_page()\nreferences are stored on the folio page while the page_ref_inc()\nreferences are stored directly in the given page. On release the folio\npage will be dereferenced too many times.\n\nThis was found while doing kTLS testing with sendfile() + ZC when the\nserved file was read from NFS on a kernel with NFS large folios support\n(commit 49b29a573da8 (\"nfs: add support for large folios\"))."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: kTLS, Fix wrong page refcounting El c\u00f3digo de manejo de tx de kTLS usa una combinaci\u00f3n de API get_page() y page_ref_inc() para incrementar la referencia de p\u00e1gina. Pero en la ruta de lanzamiento (mlx5e_ktls_tx_handle_resync_dump_comp()), solo se usa put_page(). Este es un problema cuando se usan p\u00e1ginas de folios grandes: las referencias get_page() se almacenan en la p\u00e1gina del folio mientras que las referencias page_ref_inc() se almacenan directamente en la p\u00e1gina dada. En el lanzamiento, la p\u00e1gina del folio se desreferenciar\u00e1 demasiadas veces. Esto se encontr\u00f3 al hacer pruebas de kTLS con sendfile() + ZC cuando el archivo servido se ley\u00f3 desde NFS en un kernel con soporte para folios grandes de NFS (commit 49b29a573da8 (\"nfs: agregar soporte para folios grandes\"))."
