CVE-2026-98453 in Linux
Summary
by MITRE • 10/18/2026
In the Linux kernel, the following vulnerability has been resolved:
smb: client: close handle after create-context parsing failure
SMB2_open() accounts a successful CREATE response as a remote open before parsing its create contexts. If smb2_parse_contexts() rejects malformed context data, SMB2_open() returns without closing the handle, leaving the server-side handle open and num_remote_opens elevated.
Close the handle after a post-CREATE context parsing failure so the error path releases the remote resource and balances the open count.
