Vulnerability Title
media: chips-media: wave5: Fix memory leak on codec_info allocation failure
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix memory leak on codec_info allocation failure In wave5_vpu_open_enc() and wave5_vpu_open_dec(), a vpu instance is allocated via kzalloc(). If the subsequent allocation for inst->codec_info fails, the functions return -ENOMEM without freeing the previously allocated instance, causing a memory leak. Fix this by calling kfree() on the instance in this error path to ensure it is properly released.
