"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nriscv: ptrace: Zero-initialize regset buffers before copyin\n\nuser_regset_copyin() only copies `count` bytes, so a PTRACE_SETREGSET\nrequest with a short iov_len leaves the rest of the stack buffer\nuninitialized. In riscv_vr_set() that garbage is validated and copied\ninto the target's vstate, and in riscv_cfi_set() it can be stored as\nthe target's shadow stack pointer. Zero both buffers, as the get path\nalready does."
