CVE-2023-53177

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: hi846: fix usage of pm_runtime_get_if_in_use()<br /> <br /> pm_runtime_get_if_in_use() does not only return nonzero values when<br /> the device is in use, it can return a negative errno too.<br /> <br /> And especially during resuming from system suspend, when runtime pm<br /> is not yet up again, -EAGAIN is being returned, so the subsequent<br /> pm_runtime_put() call results in a refcount underflow.<br /> <br /> Fix system-resume by handling -EAGAIN of pm_runtime_get_if_in_use().
