Hi Salvatore, It reproduces on a pristine 6.12.113 from kernel.org, and it turns out it was already reported upstream on 2 October in a stable@ thread. Our test results (pristine kernel, revert of ad812805fea7, and the 6.12 backport of aca1f2d5de17 + 62e72d2cf702 that the stable maintainers asked for) are in our reply there, also copied to this bug: https://lore.kernel.org/stable/patp264mb48180d3dff94fb287d09ce64e0...@patp264mb4818.frap264.prod.outlook.com/ aca1f2d5de17 is in 6.18.56; 6.12.y, 6.6.y and 6.1.y are waiting for tested backports. Bookworm is likely affected too: 6.1.188+ carries the same xarray change without the fix (code reading, not tested). Thomas Mischler
