"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring: fix possible deadlock in io_register_iowq_max_workers()\n\nThe io_register_iowq_max_workers() function calls io_put_sq_data(),\nwhich acquires the sqd->lock without releasing the uring_lock.\nSimilar to the commit 009ad9f0c6ee (\"io_uring: drop ctx->uring_lock\nbefore acquiring sqd->lock\"), this can lead to a potential deadlock\nsituation.\n\nTo resolve this issue, the uring_lock is released before calling\nio_put_sq_data(), and then it is re-acquired after the function call.\n\nThis change ensures that the locks are acquired in the correct\norder, preventing the possibility of a deadlock."

"value": "En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: io_uring: soluciona posible punto muerto en io_register_iowq_max_workers() La funci\u00f3n io_register_iowq_max_workers() llama a io_put_sq_data(), que adquiere el sqd->lock sin liberar uring_lock. De manera similar a la confirmaci\u00f3n 009ad9f0c6ee (\"io_uring: drop ctx->uring_lock before adquiring sqd->lock\"), esto puede conducir a una posible situaci\u00f3n de punto muerto. Para resolver este problema, uring_lock se libera antes de llamar a io_put_sq_data() y luego se vuelve a adquirir despu\u00e9s de la llamada a la funci\u00f3n. Este cambio garantiza que los bloqueos se adquieran en el orden correcto, evitando la posibilidad de un punto muerto."
