"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/boot: Avoid IPL parameter append past command line\n\nA command line may occupy all but the terminating byte of\nCOMMAND_LINE_SIZE. In that case append_ipl_block_parm() passes a zero size\nto the IPL parameter conversion helpers and points the destination one\nbyte past early_command_line. The helpers subtract one from the unsigned\nsize and write the converted parameter outside the command line buffer.\n\nConvert the IPL parameter in the command line parsing buffer first. A\nparameter beginning with '=' can then replace the existing command line\nregardless of its length, while other parameters are appended only when\nspace remains."
