Details

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:
