Description
In the Linux kernel, the following vulnerability has been resolved:
ionic: catch failure from devlink_alloc
Add a check for NULL on the alloc return. If devlink_alloc() fails and
we try to use devlink_priv() on the NULL return, the kernel gets very
unhappy and panics. With this fix, the driver load will still fail,
but at least it won't panic the kernel.
Affected configurations
• linux linux kernel (>= 5.4 < 5.15.112)
• linux linux kernel (>= 5.16 < 6.1.29)
• linux linux kernel (>= 6.2 < 6.2.16)
• linux linux kernel (>= 6.3 < 6.3.3)
