Severity CVSS v4.0:
Pending analysis
Type:
CWE-190 Integer Overflow or Wraparound
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NFSD: Prevent a potential integer overflow<br /> <br /> If the tag length is &gt;= U32_MAX - 3 then the "length + 4" addition<br /> can result in an integer overflow. Address this by splitting the<br /> decoding into several steps so that decode_cb_compound4res() does<br /> not have to perform arithmetic on the unsafe length value.
