Description

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix memory leak in query_regdb_file() In the function query_regdb_file() the alpha2 parameter is duplicated using kmemdup() and subsequently freed in regdb_fw_cb(). However, request_firmware_nowait() can fail without calling regdb_fw_cb() and thus leak memory.

Affected configurations

• linux linux kernel (>= 4.15 < 4.19.267) • linux linux kernel (>= 4.20 < 5.4.225) • linux linux kernel (>= 5.5 < 5.10.155) • linux linux kernel (>= 5.11 < 5.15.79) • linux linux kernel (>= 5.16 < 6.0.9) • linux linux kernel 6.1
