Summary

Out-of-bounds array access in dhd_rx_frame in drivers/net/wireless/bcmdhd4358/dhd_linux.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allows an attacker (who has obtained code execution on the Wi-Fi chip) to cause invalid accesses to operating system memory due to improper validation of the network interface index provided by the Wi-Fi chip's firmware.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
