CVE-2022-49608

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:
26/02/2025
Last modified:
01/10/2025

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pinctrl: ralink: Check for null return of devm_kcalloc<br /> <br /> Because of the possible failure of the allocation, data-&gt;domains might<br /> be NULL pointer and will cause the dereference of the NULL pointer<br /> later.<br /> Therefore, it might be better to check it and directly return -ENOMEM<br /> without releasing data manually if fails, because the comment of the<br /> devm_kmalloc() says "Memory allocated with this function is<br /> automatically freed on driver detach.".
