CVE-2024-39464: media: v4l: async: Fix notifier list entry init
In the Linux kernel, the following vulnerability has been resolved:
media: v4l: async: Fix notifier list entry init
struct v4l2asyncnotifier has several listhead members, but only waitinglist and donelist are initialized. notifierentry was kept 'zeroed' leading to an uninitialized listhead. This results in a NULL-pointer dereference if csi2asyncregister() fails, e.g. node for remote endpoint is disabled, and returns -ENOTCONN. The following calls to v4l2asyncnfunregister() results in a NULL pointer dereference. Add the missing list head initializer.
