| Subject: CVE-2025-37881: usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev() |
| |
| The variable d->name, returned by devm_kasprintf(), could be NULL. |
| A pointer check is added to prevent potential NULL pointer dereference. |
| This is similar to the fix in commit 3027e7b15b02 |
| ("ice: Fix some null pointer dereference issues in ice_ptp.c"). |
| |
| This issue is found by our static analysis tool |
| |
| The Linux kernel CVE team has assigned CVE-2025-37881 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
