CVE-2026-31706

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB server. An authenticated client can exploit this vulnerability by manipulating the numaces value within the parent directory's security.NTACL extended attribute. This manipulation causes ksmbd to attempt an excessivel...

CVE-2026-31706

In ksmbd (Linux kernel), CVE-2026-31706 is due to a validation flaw in smb_inherit_dacl(): the on-disk num_aces from a parent directory’s security.NTACL is trusted to size a heap allocation (kmalloc(sizeof(struct smb_ace) * num_aces * 2)) without verifying consistency with pdacl_size. An authenti...
