Description
In the Linux kernel, the following vulnerability has been resolved: media: cx88: Add missing unmap in snd_cx88_hw_params() In error path, add cx88_alsa_dma_unmap() to release resource acquired by cx88_alsa_dma_map().
A vulnerability exists in the Linux kernel's CX88 audio driver, specifically in the handling of Direct Memory Access (DMA) resources. The issue arises because the driver fails to properly release DMA resources in certain error conditions, which can lead to resource leaks or undefined behavior. This vulnerability affects the stable versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel, where this vulnerability has been addressed. Instructions for upgrading the kernel can be found in the official Linux kernel documentation.
