CVE-2022-48938

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

Last modified:

Description

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