CVE-2022-50178

The CVE-2022-50178 issue is in Linux kernel wifi support for rtw89 (8852a) where a negative RF calibration result in the DPK could trigger a divisor-by-zero and a core dump. The root cause is division in the calibration logic; the fix guards division by zero by having phy_div() perform division o...
