GHSA-7G5R-FQFH-59J6

Vulnerability from github – Published: 2024-04-04 09:30 – Updated: 2024-11-01 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: qcom: Fix uninitialized pointer dmactl

In the case where __lpass_get_dmactl_handle is called and the driver id dai_id is invalid the pointer dmactl is not being assigned a value, and dmactl contains a garbage value since it has not been initialized and so the null check may not work. Fix this to initialize dmactl to NULL. One could argue that modern compilers will set this to zero, but it is useful to keep this initialized as per the same way in functions __lpass_platform_codec_intf_init and lpass_cdc_dma_daiops_hw_params.

Cleans up clang scan build warning: sound/soc/qcom/lpass-cdc-dma.c:275:7: warning: Branch condition evaluates to a garbage value [core.uninitialized.Branch]

Severity ?

6.2 (Medium)
