CVE-2025-68789

Rejected by the assigning authority

Published Jan 13, 2026 · Updated Jan 13, 2026

The Linux CNA rejected this identifier, so it no longer represents a confirmed vulnerability affecting the Linux Kernel. Before rejection, the record described ibmpex_high_low_store() dereferencing unchecked driver data after a deletion race freed it. The CNA removed the affected-version and patch references, and CVE Program guidance states that rejected records should no longer be used.
