CVE-2026-68100

A flaw was found in ksmbd in the Linux kernel. An authenticated client can provide a crafted security descriptor that is not properly validated when copying Access Control Entries ACEs in the setntacldacl function. This improper validation leads to an out-of-bounds heap read, allowing the client ...
