CVE-2024-53146: NFSD: Prevent a potential integer overflow
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Prevent a potential integer overflow
If the tag length is >= U32MAX - 3 then the "length + 4" addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decodecbcompound4res() does not have to perform arithmetic on the unsafe length value.
