Prior to commit 45bf39f8df7f ("USB: core: Don't hold device lock while reading the "descriptors" sysfs file") this race couldn't occur, because the routines were mutually exclusive thanks to the device locking. Removing that locking from read_descriptors() exposed it to the race. The best way to fix the bug is to keep hub_port_init() from changing udev->descriptor once udev has been initialized and registered. Drivers expect the descriptors stored in the kernel to be immutable; we should not undermine this expectation. In fact, this change should have been made long ago. So now hub_port_init() will take an additional argument, specifying a buffer in which to store the device descriptor it reads. (If udev has not yet been initialized, the buffer pointer will be NULL and then hub_port_init() will store the device descriptor in udev as before.) This eliminates the data race responsible for the out-of-bounds read. The changes to hub_port_init() appear more extensive than they really are, because of indentation changes resulting from an attempt to avoid writing to other parts of the usb_device structure after it has been initialized. Similar changes should be made to the code that reads the BOS descriptor, but that can be handled in a separate patch later on. • https://git.kernel.org/stable/c/218925bfd5d1436e337c4f961e9c149fbe32de6d https://git.kernel.org/stable/c/77358093331e9769855140bf94a3f00ecdcf4bb1 https://git.kernel.org/stable/c/c87fb861ec185fdc578b4fdc6a05920b6a843840 https://git.kernel.org/stable/c/45bf39f8df7f05efb83b302c65ae3b9bc92b7065 https://git.kernel.org/stable/c/6badaf880edf51a2da7a439699676394dfdef3e5 https://git.kernel.org/stable/c/5f35b5d3bd6914c68f743741443dfd3a64b0e455 https://git.kernel.org/stable/c/a1e89c8b29d003a20ed2dae6bdae1598d1f23e42 https://git.kernel.org/stable/c/1bcb238c54a9c6dc4bded06b06ba7458a •
