CVE-2022-2327 HIGH

Published: 2022-07-22 | Last Modified: 2026-10-02 | Status: Analyzed

Description

io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859

io_uring usa work_flags para determinar qué identidad necesita tomar del proceso que llama para asegurarse de que es consistente con el proceso que llama cuando ejecuta IORING_OP. Algunas operaciones carecen de algunos tipos, lo que puede conllevar a un recuento de referencias incorrecto que puede llevar a una doble liberación. Recomendamos actualizar el kernel después del commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859
