| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface() |
| |
| There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and |
| the number of it's interfaces less than 4, an out-of-bounds read bug occurs |
| when parsing the interface descriptor for this device. |
| |
| Fix this by checking the number of interfaces. |

| 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: |
