| Subject: CVE-2024-44960: usb: gadget: core: Check for unset descriptor |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: gadget: core: Check for unset descriptor |
| |
| Make sure the descriptor has been set before looking at maxpacket. |
| This fixes a null pointer panic in this case. |
| |
| This may happen if the gadget doesn't properly set up the endpoint |
| for the current speed, or the gadget descriptors are malformed and |
| the descriptor for the speed/endpoint are not found. |
| |
| No current gadget driver is known to have this problem, but this |
| may cause a hard-to-find bug during development of new gadgets. |
| |
| The Linux kernel CVE team has assigned CVE-2024-44960 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: |
