Details

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.

Severity
5.5 (Medium)
