Summary
CVE-2025-40053 affecting package kernel for versions less than 6.6.112.1-2
Details

In the Linux kernel, the following vulnerability has been resolved:

net: dlink: handle copy_thresh allocation failure

The driver did not handle failure of netdev_alloc_skb_ip_align(). If the allocation failed, dereferencing skb->protocol could lead to a NULL pointer dereference.

This patch tries to allocate skb. If the allocation fails, it falls back to the normal path.

Tested-on: D-Link DGE-550T Rev-A3
