Description
In the Linux kernel, the following vulnerability has been resolved:
CDC-NCM: avoid overflow in sanity checking
A broken device may give an extreme offset like 0xFFF0
and a reasonable length for a fragment. In the sanity
check as formulated now, this will create an integer
overflow, defeating the sanity check. Both offset
and offset + len need to be checked in such a manner
that no overflow can occur.
And those quantities should be unsigned.
Affected configurations
• linux linux kernel (< 5.10.103)
• linux linux kernel (>= 5.11 < 5.15.26)
• linux linux kernel (>= 5.16 < 5.16.12)
