In the Linux kernel, the following vulnerability has been resolved:
qede: confirm skb is allocated before using
qedebuildskb() assumes buildskb() always works and goes straight to skbreserve(). However, build_skb() can fail under memory pressure. This results in a kernel panic because the skb to reserve is NULL.
Add a check in case build_skb() failed to allocate and return NULL.
The NULL return is handled correctly in callers to qedebuildskb().
