In the Linux kernel, the following vulnerability has been resolved:
io_uring/rsrc: don't rely on user vaddr alignment
There is no guaranteed alignment for user pointers, however the calculation of an offset of the first page into a folio after coalescing uses some weird bit mask logic, get rid of it.
