In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]smb: client: fix memory leak in cifs_construct_tcon()[EOL][EOL]When having a multiuser mount with domain= specified and using[EOL]cifscreds, cifs_set_cifscreds() will end up setting @ctx->domainname,[EOL]so it needs to be freed before leaving cifs_construct_tcon().[EOL][EOL]This fixes the following memory leak reported by kmemleak:[EOL][EOL]  mount.cifs //srv/share /mnt -o domain=ZELDA,multiuser,...[EOL]  su - testuser[EOL]  cifscreds add -d ZELDA -u testuser[EOL]  ...[EOL]  ls /mnt/1[EOL]  ...[EOL]  umount /mnt[EOL]  echo scan > /sys/kernel/debug/kmemleak[EOL]  cat /sys/kernel/debug/kmemleak[EOL]  unreferenced object 0xffff8881203c3f08 (size 8):[EOL]    comm "ls", pid 5060, jiffies 4307222943[EOL]    hex dump (first 8 bytes):[EOL]      5a 45 4c 44 41 00 cc cc                          ZELDA...[EOL]    backtrace (crc d109a8cf):[EOL]      __kmalloc_node_track_caller_noprof+0x572/0x710[EOL]      kstrdup+0x3a/0x70[EOL]      cifs_sb_tlink+0x1209/0x1770 [cifs][EOL]      cifs_get_fattr+0xe1/0xf50 [cifs][EOL]      cifs_get_inode_info+0xb5/0x240 [cifs][EOL]      cifs_revalidate_dentry_attr+0x2d1/0x470 [cifs][EOL]      cifs_getattr+0x28e/0x450 [cifs][EOL]      vfs_getattr_nosec+0x126/0x180[EOL]      vfs_statx+0xf6/0x220[EOL]      do_statx+0xab/0x110[EOL]      __x64_sys_statx+0xd5/0x130[EOL]      do_syscall_64+0xbb/0x380[EOL]      entry_SYSCALL_64_after_hwframe+0x77/0x7f
