  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf, riscv: Fix extable handling for arena load_acquire  emit_atomic_ld_st() returns 1 to have build_body() skip the zext after a sub-word load_acquire. The caller does \"ret = ret ?: add_exception_handler(...)\", which skips add_exception_handler() on any non-zero ret, so the extable entry is missing and a faulting PROBE_ATOMIC load_acquire oopses.  REG_DONT_CLEAR_MARKER leaves rd stale on fault, and the verifier still thinks the load overwrote it, so a program can leak it through a map.  Check ret \u003e= 0 before calling add_exception_handler(), and pass rd for LOAD_ACQ so the fault zeroes rd like a PROBE_MEM load. Return ret unchanged for the zext skip.",
