  "title": "ksmbd: bound DACL dedup walk to copied ACEs",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: bound DACL dedup walk to copied ACEs  set_ntacl_dacl() can stop copying ACEs before consuming the full input DACL when size accounting overflows.  When that happens, num_aces reflects only the ACEs that were actually copied into the output DACL, but set_posix_acl_entries_dacl() still receives nt_num_aces and uses it to walk the existing ACE array during dedup.  That makes the dedup walk scan past the copied ACE array and inspect buffer tail that does not contain valid ACEs.  Split the two meanings currently carried by the NT ACE count. Pass the number of copied NT ACEs to bound the dedup walk, and preserve the original \u0022input DACL had NT ACEs\u0022 state separately for the Everyone/default ACL fallback.  This keeps the dedup walk aligned with the ACEs that are actually present in the rebuilt DACL.",
