CVE-2025-40304

CVE-2025-40304 corresponds to a Linux kernel vulnerability in the fbdev path, where an insufficient bounds check in the function used to render text (bit_putcs) allowed an out-of-bounds write to vmalloc-ed memory when drawing near framebuffer edges. The root cause was a mismatch between the alloc...
