CVE-2024-57978 Information

Description

In the Linux kernel the following vulnerability has been resolved:

media: imx-jpeg: Fix potential error pointer dereference in detach_pm()

The proble is on the first line:

if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i]))

If jpeg->pd_dev[i] is an error pointer then passing it to pm_runtime_suspended() will lead to an Oops. The other conditions check for both error pointers and NULL but it would be more clear to use the IS_ERR_OR_NULL() check for that.
