CVE-2024-57980 Information

Description

In the Linux kernel the following vulnerability has been resolved:

media: uvcvideo: Fix double free in error path

If the uvc_status_init() function fails to allocate the int_urb it will free the dev->status pointer but doesn’t reset the pointer to NULL. This results in the kfree() call in uvc_status_cleanup() trying to double-free the memory. Fix it by resetting the dev->status pointer to NULL after freeing it.
