CVE-2024-42089

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:
29/07/2024
Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ASoC: fsl-asoc-card: set priv-&gt;pdev before using it<br /> <br /> priv-&gt;pdev pointer was set after being used in<br /> fsl_asoc_card_audmux_init().<br /> Move this assignment at the start of the probe function, so<br /> sub-functions can correctly use pdev through priv.<br /> <br /> fsl_asoc_card_audmux_init() dereferences priv-&gt;pdev to get access to the<br /> dev struct, used with dev_err macros.<br /> As priv is zero-initialised, there would be a NULL pointer dereference.<br /> Note that if priv-&gt;dev is dereferenced before assignment but never used,<br /> for example if there is no error to be printed, the driver won&amp;#39;t crash<br /> probably due to compiler optimisations.
