CVE-2022-48703

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue arises when the GDDV returns a package with a buffer of zero length, causing kmemdup() to return ZERO SIZE PTR (0x10). This leads to a NULL pointer dereference problem in data vault read() when accessing the 0x10 value in data vault. The patch resolves this by using ZERO OR NULL PTR() to check for ZERO SIZE PTR or NULL values in data vault.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
