  "details": "In the Linux kernel, the following vulnerability has been resolved:  LoongArch: BPF: Refactor jump offset calculation in tail call  The old macro-based jmp_offset calculation derives the jump distance from a stale prior-pass code stride, which can lead to wrong branch offsets and soft lockups under extra JIT passes.  Fix this by calculating the offset directly on the absolute target: \"ctx-\u003eoffset[insn + 1] - ctx-\u003eidx\".  To avoid a false 16-bit range check abort during size estimation, add a \"ctx-\u003eimage == NULL\" guard to inject a safe dummy offset.",
