"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntls: fix use-after-free on failed backlog decryption\n\nWhen the decrypt request goes to the backlog and crypto_aead_decrypt\nreturns -EBUSY, tls_do_decryption will wait until all async\ndecryptions have completed. If one of them fails, tls_do_decryption\nwill return -EBADMSG and tls_decrypt_sg jumps to the error path,\nreleasing all the pages. But the pages have been passed to the async\ncallback, and have already been released by tls_decrypt_done.\n\nThe only true async case is when crypto_aead_decrypt returns\n -EINPROGRESS. With -EBUSY, we already waited so we can tell\ntls_sw_recvmsg that the data is available for immediate copy, but we\nneed to notify tls_decrypt_sg (via the new ->async_done flag) that the\nmemory has already been released."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: tls: corrige el use-after-free en el descifrado fallido del trabajo pendiente Cuando la solicitud de descifrado va al trabajo pendiente y crypto_aead_decrypt devuelve -EBUSY, tls_do_decryption esperar\u00e1 hasta que se hayan completado todos los descifrados as\u00edncronos. Si uno de ellos falla, tls_do_decryption devolver\u00e1 -EBADMSG y tls_decrypt_sg salta a la ruta del error, liberando todas las p\u00e1ginas. Pero las p\u00e1ginas se pasaron a la devoluci\u00f3n de llamada as\u00edncrona y tls_decrypt_done ya las public\u00f3. El \u00fanico caso as\u00edncrono verdadero es cuando crypto_aead_decrypt devuelve -EINPROGRESS. Con -EBUSY, ya esperamos para poder decirle a tls_sw_recvmsg que los datos est\u00e1n disponibles para copia inmediata, pero debemos notificar a tls_decrypt_sg (a trav\u00e9s del nuevo indicador ->async_done) que la memoria ya ha sido liberada."
