Let's look at the details. + +The user mentioned that running a tutorial caused an issue where `sd_init()` generates a SIGSEGV when passed NULL. They provided a link to the commit in sd.c and noted that reverting to tag v1.6.1 fixed it. + +Looking at the code, `sd_init()` is called with potentially a NULL bs (BlockDriverState). Inside `sd_init()`, there's a line where `qemu_blockalign(bs, 512)` is called. If bs is NULL, this function would likely crash because passing NULL to functions expecting non-NULL pointers can cause segmentation faults. + +The error occurs in block.c at `bdrv_is_read_only(bs)`. The problem stems from allowing a NULL bs into `sd_init()`, which then leads to accessing `bs->read_only` when it's null, causing SIGSEGV. + +This issue is related to how the code handles the BlockDriverState. Since it's about improper handling of pointers and function arguments leading to a crash, it doesn't fit categories like 'network' or 'graphic'. Instead, it's more about incorrect usage of pointers in block driver operations. + +So, the category should be 'block'. +</think> + +The bug involves passing a NULL pointer to `sd_init()`, causing a SIGSEGV when accessing `bs->read_only`.
