Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: Use READ_ONCE_NOCHECK in imprecise unwinding stack mode
When CONFIG_FRAME_POINTER is unset, the stack unwinding function
walk_stackframe randomly reads the stack and then, when KASAN is enabled,
it can lead to the following backtrace:
