CVE-2026-74396

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/mlx5: Fix UMR XLT cleanup on ODP populate failure<br /> <br /> mlx5r_umr_update_xlt() allocates and DMA maps an XLT buffer with<br /> mlx5r_umr_create_xlt(). The buffer is released by the common cleanup path<br /> through mlx5r_umr_unmap_free_xlt().<br /> <br /> After mlx5_odp_populate_xlt() became fallible, its error path returned<br /> directly and skipped that cleanup. This leaks the XLT DMA mapping and<br /> buffer. If the emergency XLT page was used, it also leaves<br /> xlt_emergency_page_mutex locked.<br /> <br /> Break out of the loop so execution falls through the existing cleanup path.
