NFSD: Prevent a potential integer overflow

State: Published
Severity: 9.1 Critical
Published: Dec 24, 2024
Updated: Aug 5, 2026
Reserved: Nov 19, 2024

Description

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

NFSD: Prevent a potential integer overflow

If the tag length is >= U32_MAX - 3 then the "length + 4" addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decode_cb_compound4res() does not have to perform arithmetic on the unsafe length value.
