CVE-2025-38612
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
staging: fbtft: fix potential memory leak in fbtft_framebuffer_alloc()
In the error paths after fb_info structure is successfully allocated, the memory allocated in fb_deferred_io_init() for info->pagerefs is not freed. Fix that by adding the cleanup function on the error path.
