 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:smb: client: fix OOBs when building SMB2_IOCTL requestWhen using encryption, either enforced by the server or when using seal  mount option, the client will squash all compound request buffersdown for encryption into a single iov in smb2_set_next_command().SMB2_ioctl_init() allocates a small buffer (448 bytes) to hold theSMB2_IOCTL request in the first iov, and if the user passes an inputbuffer that is greater than 328 bytes, smb2_set_next_command() willend up writing off the end of @rqst->iov[0].iov_base as shown below:  mount.cifs //srv/share /mnt -o ...,seal  ln -s $(perl -e  print( a )for 1..1024 ) /mnt/link  BUG: KASAN: slab-out-of-bounds in  smb2_set_next_command.cold+0x1d6/0x24c [cifs]  Write of size 4116 at addr ffff8881148fcab8 by task ln/859  CPU: 1 UID: 0 PID: 859 Comm: ln Not tainted 6.12.0-rc3 #1  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS  1.16.3-2.fc40 04/01/2014  Call Trace:   <TASK>   dump_stack_lvl+0x5d/0x80   ? smb2_set_next_command.cold+0x1d6/0x24c [cifs]   print_report+0x156/0x4d9   ? smb2_set_next_command.cold+0x1d6/0x24c [cifs]   ? __virt_addr_valid+0x145/0x310   ? __phys_addr+0x46/0x90   ? smb2_set_next_command.cold+0x1d6/0x24c [cifs]   kasan_report+0xda/0x110   ? smb2_set_next_command.cold+0x1d6/0x24c [cifs]   kasan_check_range+0x10f/0x1f0   __asan_memcpy+0x3c/0x60   smb2_set_next_command.cold+0x1d6/0x24c [cifs]   smb2_compound_op+0x238c/0x3840 [cifs]   ? kasan_save_track+0x14/0x30   ? kasan_save_free_info+0x3b/0x70   ? vfs_symlink+0x1a1/0x2c0   ? do_symlinkat+0x108/0x1c0   ? __pfx_smb2_compound_op+0x10/0x10 [cifs]   ? kmem_cache_free+0x118/0x3e0   ? cifs_get_writable_path+0xeb/0x1a0 [cifs]   smb2_get_reparse_inode+0x423/0x540 [cifs]   ? __pfx_smb2_get_reparse_inode+0x10/0x10 [cifs]   ? rcu_is_watching+0x20/0x50   ? __kmalloc_noprof+0x37c/0x480   ? smb2_create_reparse_symlink+0x257/0x490 [cifs]   ? smb2_create_reparse_symlink+0x38f/0x490 [cifs]   smb2_create_reparse_symlink+0x38f/0x490 [cifs]   ? __pfx_smb2_create_reparse_symlink+0x10/0x10 [cifs]   ? find_held_lock+0x8a/0xa0   ? hlock_class+0x32/0xb0   ? __build_path_from_dentry_optional_prefix+0x19d/0x2e0 [cifs]   cifs_symlink+0x24f/0x960 [cifs]   ? __pfx_make_vfsuid+0x10/0x10   ? __pfx_cifs_symlink+0x10/0x10 [cifs]   ? make_vfsgid+0x6b/0xc0   ? generic_permission+0x96/0x2d0   vfs_symlink+0x1a1/0x2c0   do_symlinkat+0x108/0x1c0   ? __pfx_do_symlinkat+0x10/0x10   ? strncpy_from_user+0xaa/0x160   __x64_sys_symlinkat+0xb9/0xf0   do_syscall_64+0xbb/0x1d0   entry_SYSCALL_64_after_hwframe+0x77/0x7f  RIP: 0033:0x7f08d75c13bb
