CVE-2025-37822

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.
