Description OSIDB Bzimport 2024-12-29 12:01:49 UTC
In the Linux kernel, the following vulnerability has been resolved:

fbdev: sh7760fb: Fix a possible memory leak in sh7760fb_alloc_mem()

When information such as info->screen_base is not ready, calling
sh7760fb_free_mem() does not release memory correctly. Call
dma_free_coherent() instead.
