Doc Text:	A flaw was found in the Linux kernel's wave5 media driver. When a `vpu` instance is allocated, and a subsequent allocation for `codec_info` fails, the driver returns an error without freeing the previously allocated `vpu` instance. This oversight leads to a memory leak, which could potentially impact system stability or resource availability over time.	Story Points:	---

Description OSIDB Bzimport 2026-05-27 15:05:12 UTC

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.
