| Subject: CVE-2023-52655: usb: aqc111: check packet for fixup for true limit |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb: aqc111: check packet for fixup for true limit |
| |
| If a device sends a packet that is inbetween 0 |
| and sizeof(u64) the value passed to skb_trim() |
| as length will wrap around ending up as some very |
| large value. |
| |
| The driver will then proceed to parse the header |
| located at that position, which will either oops or |
| process some random value. |
| |
| The fix is to check against sizeof(u64) rather than |
| 0, which the driver currently does. The issue exists |
| since the introduction of the driver. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52655 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/84f2e5b3e70f08fce3cb1ff73414631c5e490204 |
