| Internal Reference Number | Description |
| 4357048 | Description: Fixed a security vulnerability detailed in CVE-2025-23263. For more information, refer to the security bulletin: https://nvidia.custhelp.com/app/answers/detail/a_id/5654. |
| Keywords: VGT+ | |
| Discovered in Release: 23.10-4.0.9.1 | |
| Fixed in Release: 23.10-5.1.4.0 | |
| 4410029 | Description: Fixed an issue where installing mlnx-ofa_kernel drivers on SLES 15 SP5 with kernel version 5.14.21-150500.55.68-default (and newer) failed due to weak-modules falling back to the original inbox modules. The failure was caused by a mismatch: the original build kernel (5.14.21-150500.53-default) did not include the mana_ib driver, so no dummy module was provided, while the newer kernel did include it. This mismatch led to weak-modules sanity check errors due to the presence of the inbox mana_ib driver. |

| Discovered in Release: 23.10-4.0.9.1 | |
| Fixed in Release: 23.10-5.1.4.0 | |
| 4471811 | Description: Resolved NVMe driver compilation issue on Linux kernel version 6.6.87. |
| Keywords: NVMe driver | |
| Discovered in Release: 23.10-4.0.9.1 | |
| Fixed in Release: 23.10-5.1.4.0 | |
| 4253229 | Description: Fixed a race condition between the firmware syndrome report and driver initialization during boot. |
| Keywords: Race condition | |
| Discovered in Release: 23.10-4.0.9.1 | |
| Fixed in Release: 23.10-5.1.4.0 | |
| 4442965 | Description: Fixed performance degradation on older kernel versions using RX cache, particularly on slower ARM CPUs with larger RX buffers. The issue was caused by the driver attempting to allocate new RX pages too quickly, leading to head-of-line blocking in the RX cache. The fix improves RX cache usage by triggering page allocation for a bulk of at least 2 WQEs, allowing the application more time to process packets and return buffers to the RX cache, thereby reducing blocking and enhancing performance. |
