CVE-2024-56746

Summary

CVE-2024-56746 is a recently identified vulnerability in the Linux kernel. Specifically, it affects the sh7760fb driver, where a memory leak in the function sh7760fb_alloc_mem() may occur. This issue arises when certain required information, such as 'info->screen_base', is not yet available. As a result, calling sh7760fb_free_mem() does not effectively release allocated memory, leading to a potential memory leak. To address this issue, the recommended solution is to use dma_free_coherent() instead for memory deallocation in applicable scenarios.
