| Subject: CVE-2023-52742: net: USB: Fix wrong-direction WARNING in plusb.c |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: USB: Fix wrong-direction WARNING in plusb.c |
| |
| The syzbot fuzzer detected a bug in the plusb network driver: A |
| zero-length control-OUT transfer was treated as a read instead of a |
| write. In modern kernels this error provokes a WARNING: |
| |
| usb 1-1: BOGUS control dir, pipe 80000280 doesn't match bRequestType c0 |
| WARNING: CPU: 0 PID: 4645 at drivers/usb/core/urb.c:411 |

| |
| The fix is to call usbnet_write_cmd() instead of usbnet_read_cmd() and |
| remove the USB_DIR_IN flag. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52742 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: |
