CVE-2026-90153

A flaw was found in ksmbd, the in-kernel SMB3 server for Linux. The smbcheckpermdacl function incorrectly validates Access Control Entry ACE walks by using the remaining security descriptor length instead of the declared Discretionary Access Control List DACL size. This allows a remote attacker t...
