Loading vulnerability…
A flaw in the Linux kernel mlxsw Spectrum ACL ERP component affects ACL mask aggregation and rehashing on Spectrum-2 and newer ASICs. During hint generation, the driver compared aggregation objects using only their masks and ignored whether an object belonged to algorithmic TCAM or circuit TCAM. Recursive hint resolution could consequently select an object from the other TCAM class and create unsupported nested objagg objects, triggering an objagg object-parent assignment warning during ACL region migration. The fix removes the custom object-comparison function so objagg lookups return exact object matches.
