CVE-2025-39751

Rejected by assigning authority

Published Sep 11, 2025 · Updated Sep 11, 2025

The CVE Numbering Authority rejected this Linux Kernel record on October 6, 2025, so it no longer identifies a vulnerability. The withdrawn description had attributed a 44-byte buffer overflow to an unbounded sprintf call in add_tuning_control. Because the identifier and record are invalid, no current affected-version, exploitation, or operational-impact claim remains attributable to it.
