GHSA-FW2P-R2V5-6JJQ

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-05-07 15:31

Details

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.

Severity ?

5.5 (Medium)
