| Subject: CVE-2024-26964: usb: xhci: Add error handling in xhci_map_urb_for_dma |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: xhci: Add error handling in xhci_map_urb_for_dma |
| |
| Currently xhci_map_urb_for_dma() creates a temporary buffer and copies |
| the SG list to the new linear buffer. But if the kzalloc_node() fails, |
| then the following sg_pcopy_to_buffer() can lead to crash since it |
| tries to memcpy to NULL pointer. |
| |
| So return -ENOMEM if kzalloc returns null pointer. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26964 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: |
| https://git.kernel.org/stable/c/4a49d24fdec0a802aa686a567a3989a9fdf4e5dd |
