CVE-2026-68099 ksmbd: restore DACL size on check_add_overflow() to avoid malformed ACL

In the Linux kernel, the following vulnerability has been resolved: ksmbd: restore DACL size on checkaddoverflow to avoid malformed ACL checkaddoverflow unconditionally writes the truncated sum into d even on overflow, per its contract in include/linux/overflow.h. The four checkaddoverflow guards...

CVE-2026-68099

The CVE-2026-68099 vulnerability is in ksmbd within the Linux kernel, where check_add_overflow() could cause an on-wire NT ACL to be malformed. In the affected DACL builders (set_posix_acl_entries_dacl() and set_ntacl_dacl()), overflow handling previously allowed the loop to break while the desti...

CVE-2026-68097 ksmbd: validate ACE size against SID sub-authorities

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate ACE size against SID sub-authorities setntacldacl validates sid.numsubauth before copying an ACE, but does not verify that the declared ACE size contains all sub-authorities described by that field. An undersized...

CVE-2026-68097

Summary: CVE-2026-68097 affects the Linux kernel ksmbd path handling POSIX ACLs. The root cause is a check failure in ACE validation: set_ntacl_dacl() validates sid.num_subauth but does not ensure the declared ACE size can contain all sub-authorities, allowing an undersized ACE to be copied and l...

CVE-2026-68083

CVE-2026-68083 affects ksmbd (Linux kernel in-kernel SMB server). The issue is a path-resolution bug in ksmbd_vfs_kern_path_create() where an SMB2 create/mkdir/hardlink path can leverage a ".." component to escape the share, because the rooted open lookup uses LOOKUP_BENEATH for the SMB2 path but...
