  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Preserve pointer state for commuted arithmetic\n\nWhen scalar += pointer is handled in adjust_ptr_min_max_vals(), the\ndestination register inherits the pointer state from the source pointer.\nCopying only selected fields is fragile because pointer provenance is\ntracked by several bpf_reg_state fields.\n\nUse the caller's temporary offset register to preserve the scalar operand\nwhile replacing the destination with the full pointer state. This preserves\nthe frame number for PTR_TO_STACK registers and keeps parent identity\nfields consistent.",
