  "description": "In the Linux kernel, the following vulnerability has been resolved:  LoongArch: Fix address space mismatch in kexec command line lookup  When searching the loaded segments for the \u0022kexec\u0022 command line marker, the kexec_load(2) path (file_mode == 0) passes the user-space segment buffer straight to strncmp() through a bogus (char __user *) cast. This dereferences a user pointer in kernel context, which is wrong and is flagged by sparse:    arch/loongarch/kernel/machine_kexec.c:84:51: sparse: incorrect type in   argument 2 (different address spaces) @@ expected char const * @@ got   char [noderef] __user *  Here copy the marker-sized prefix of each segment into a small on-stack buffer with copy_from_user() before comparing, and skip segments that fault. The subsequent copy_from_user() that stages the full command line into the safe area is left unchanged.",
