CVE-2026-45928 Details
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.
A memory leak vulnerability has been identified in the Linux kernel's handling of Wave5 VPU codecs. When opening a VPU instance for encoding or decoding, the kernel allocates memory for the instance. However, if the allocation of codec information fails, the function returns an error without freeing the previously allocated memory for the VPU instance. This oversight creates a memory leak. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users can apply the latest patches available in the Linux kernel stable tree to mitigate this issue.
