Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> riscv/purgatory: align riscv_kernel_entry<br /> <br /> When alignment handling is delegated to the kernel, everything must be<br /> word-aligned in purgatory, since the trap handler is then set to the<br /> kexec one. Without the alignment, hitting the exception would<br /> ultimately crash. On other occasions, the kernel&amp;#39;s handler would take<br /> care of exceptions.<br /> This has been tested on a JH7110 SoC with oreboot and its SBI delegating<br /> unaligned access exceptions and the kernel configured to handle them.
