Type:
CWE-476
NULL Pointer Dereference
Publication date:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ASoC: amd: acp: Fix incorrect retrival of acp_chip_info<br />
<br />
Use dev_get_drvdata(dev->parent) instead of dev_get_platdata(dev)<br />
to correctly obtain acp_chip_info members in the acp I2S driver.<br />
Previously, some members were not updated properly due to incorrect<br />
data access, which could potentially lead to null pointer<br />
dereferences.<br />
<br />
This issue was missed in the earlier commit<br />
("ASoC: amd: acp: Fix NULL pointer deref in acp_i2s_set_tdm_slot"),<br />
which only addressed set_tdm_slot(). This change ensures that all<br />
relevant functions correctly retrieve acp_chip_info, preventing<br />
further null pointer dereference issues.
