CVE-2026-64393

The CVE-2026-64393 issue affects the Linux kernel ksmbd component. SMB2 SET_INFO handlers performed path-based VFS checks using the current ksmbd worker credentials rather than the credentials that opened the handle, potentially bypassing security checks. The fix captures the opener credentials a...

CVE-2026-64392

The CVE-2026-64392 entry concerns the Linux kernel ksmbd delete-on-close path. The underlying issue was that delete-on-close could execute unlink and ADS xattr removal with ksmbd worker credentials rather than the credentials captured at file open, allowing potential permission checks bypass. The...
