Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> riscv: uprobes: Add missing fence.i after building the XOL buffer<br /> <br /> The XOL (execute out-of-line) buffer is used to single-step the<br /> replaced instruction(s) for uprobes. The RISC-V port was missing a<br /> proper fence.i (i$ flushing) after constructing the XOL buffer, which<br /> can result in incorrect execution of stale/broken instructions.<br /> <br /> This was found running the BPF selftests "test_progs:<br /> uprobe_autoattach, attach_probe" on the Spacemit K1/X60, where the<br /> uprobes tests randomly blew up.
