FKIE_CVE-2024-42089
Vulnerability from fkie_nvd - Published: 2024-07-29 17:15 - Updated: 2026-06-17 07:48
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: fsl-asoc-card: set priv->pdev before using it
priv->pdev pointer was set after being used in
fsl_asoc_card_audmux_init().
Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.
fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.
