CVE-2026-90010Hinoki check available

Local memory corruption via oversized sense copy

Published Sep 16, 2026 · Updated Sep 16, 2026

Out-of-bounds write in the SCSI bsg io_uring path in Linux 7.1 allows local users to overwrite a too-small response buffer. Completion copies scmd->sense_len bytes into the user response without capping the copy at max_response_len. Exploitation requires local access to a bsg device and valid SCSI sense data longer than that limit; published material establishes the overrun but no further consequence.
