Linux Distros Unpatched Vulnerability : CVE-2026-68381

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ksmbd: pin conn during async oplock break notification smb2oplockbreaknoti and smb2leasebreaknoti store a ksmbdconn pointer in an async ksmbdwork and then queue...

CVE-2026-68083

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB server. An authenticated client could exploit a path resolution error, specifically in the ksmbdvfskernpathcreate function. This vulnerability allows a client to use ".." components in a path to escape the intended...
