简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- s390/fpu修复 fpu_vstl() 中的误报 kmsan 报告运行 ping 命令时检测到误报 kmsan 报告。内联汇编指令“vstl”可根据“index”参数的值写入不同数量的字节。如果“index” > 0则“vstl”至少会写入 2 个字节。 clang 根据内联汇编限制生成 kmsan 写入帮助程序调用。会在编译时评估约束但“index”参数的值仅在运行时知晓。 clang 当前生成对 __msan_instrument_asm_store 的调用大小为 1 字节。手动调用 kmsan 函数以指示写入的正确字节数并修复误报报告。此更改修复了以下 kmsan 报告 [ 36.563119] ======================================= ============== [ 36.563594] BUGKMSANvirtqueue_add+0x35c6/0x7c70 中的 uninit-value [ 36.563852] virtqueue_add+0x35c6/0x7c70 [ 36.564016] virtqueue_add_outbuf+0xa0/0xb0 [ 36.564266] start_xmit+0x288c/0x4a20 [ 36.564460] dev_hard_start_xmit+0x302/0x900 [ 36.564649] sch_direct_xmit+0x340/0xea0 [ 36.564894]
