What is CVE-2026-45928?

CVE-2026-45928 is a medium-severity denial of service vulnerability in Linux kernel, published on 27 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-401
