CVE-2023-54061

Kernel oops via misplaced exception table annotation

Published Dec 24, 2025 · Updated Dec 24, 2025

The rejected Linux Kernel 6.1 record described a local kernel oops caused by a faulting user-memory clear operation. In clear_user_rep_good(), the exception-table entry pointed to the register move before the final rep movsb instead of the user-accessing instruction, so a page fault bypassed fixup and produced an oops rather than -EFAULT. Kernel.org subsequently rejected the CVE, so it no longer supports a confirmed vulnerability or affected-product claim.
