In the Linux kernel, the following vulnerability has been resolved: net: marvell: prestera: fix NULL dereference on devlink_alloc() failure devlink_alloc() may return NULL on allocation failure, but prestera_devlink_alloc() unconditionally calls devlink_priv() on the returned pointer. This leads to a NULL pointer dereference if devlink allocation fails. Add a check for a NULL devlink pointer and return NULL early to avoid the crash.
