| Subject: CVE-2025-37990: wifi: brcm80211: fmac: Add error handling for brcmf_usb_dl_writeimage() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| wifi: brcm80211: fmac: Add error handling for brcmf_usb_dl_writeimage() |
| |
| The function brcmf_usb_dl_writeimage() calls the function |
| brcmf_usb_dl_cmd() but dose not check its return value. The |
| 'state.state' and the 'state.bytes' are uninitialized if the |
| function brcmf_usb_dl_cmd() fails. It is dangerous to use |
| uninitialized variables in the conditions. |
| |
| Add error handling for brcmf_usb_dl_cmd() to jump to error |
| handling path if the brcmf_usb_dl_cmd() fails and the |
| 'state.state' and the 'state.bytes' are uninitialized. |
| |
| Improve the error message to report more detailed error |
| information. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37990 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: |
