## Overview

In the Linux kernel, the following vulnerability has been resolved:

riscv: uprobes: Add missing fence.i after building the XOL buffer

The XOL (execute out-of-line) buffer is used to single-step the
replaced instruction(s) for uprobes. The RISC-V port was missing a
proper fence.i (i$ flushing) after constructing the XOL buffer, which
can result in incorrect execution of stale/broken instructions.

This was found running the BPF selftests "test_progs:
uprobe_autoattach, attach_probe" on the Spacemit K1/X60, where the
uprobes tests randomly blew up.

## Affected

- `linux_kernel >= 5.12, < 6.12.26`
- `linux_kernel >= 6.13, < 6.14.5`
- `linux_kernel = 6.15`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.14.5`
