Vulnerability description

DayBreach CVE AI Research

CVE-2026-80880 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Properly support implicit ODP rereg_mr Due to all the child mkeys in the implicit ODP configuration we cannot change anything in place for the parent mkey. Instead the whole thing needs to be rebuilt if any change is requested. If the user does not specify a translation then force the implicit values which will then fall through the logic into mlx5_ib_reg_user_mr() to allocate a completely new MR. Since implicit children were also touching the mr->pd, this removes another case where the access was racy.
