CVE-2026-43110

Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: validate bsscfg indices in IF events

brcmf_fweh_handle_if_event() validates the firmware-provided interface index before it touches drvr->iflist[], but it still uses the raw bsscfgidx field as an array index without a matching range check.

Reject IF events whose bsscfg index does not fit in drvr->iflist[] before indexing the interface array.

[add missing wifi prefix]
