Descriptions

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: Fix error code in iwl_op_mode_dvm_start() Preserve the error code if iwl_setup_deferred_work() fails. The current
code returns ERR_PTR(0) (which is NULL) on this path. I believe the
missing error code potentially leads to a use after free involving
debugfs.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: iwlwifi: Se corrige el código de error en iwl_op_mode_dvm_start(). Se conserva el código de error si iwl_setup_deferred_work() falla. El código actual devuelve ERR_PTR(0) (que es NULL) en esta ruta. Creo que la falta del código de error podría provocar un uso posterior a la liberación que involucre debugfs.

This update provides the initial livepatch for this kernel update. This update does not contain any fixes and will be updated with livepatches later.
