| Subject: CVE-2024-35822: usb: udc: remove warning when queue disabled ep |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: udc: remove warning when queue disabled ep |
| |
| It is possible trigger below warning message from mass storage function, |
| |
| WARNING: CPU: 6 PID: 3839 at drivers/usb/gadget/udc/core.c:294 usb_ep_queue+0x7c/0x104 |
| pc : usb_ep_queue+0x7c/0x104 |
| lr : fsg_main_thread+0x494/0x1b3c |
| |
| Root cause is mass storage function try to queue request from main thread, |
| but other thread may already disable ep when function disable. |
| |
| As there is no function failure in the driver, in order to avoid effort |
| to fix warning, change WARN_ON_ONCE() in usb_ep_queue() to pr_debug(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-35822 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: |
