An official patch is available and should be applied to affected Linux kernel versions. The vendor advisory from Ubuntu confirms that this issue is fixed in updated kernel packages. Systems running affected versions should upgrade to the patched kernel releases to remediate this vulnerability.
Description
A medium severity vulnerability (CVE-2025-71297) in the Linux kernel's rtw88 wifi driver for the 8822b chipset was resolved. The issue involved a WARNING triggered when the rtw8822b_set_antenna() function was called from userspace while the chip was powered off, causing unexpected reads from RF registers. This could lead to system instability or crashes. The fix ensures that rtw8822b_config_trx_mode() is only called when the chip is powered on. The vulnerability affects multiple Linux kernel versions prior to 6.8.0-1060.63~22.04.1 and related builds. An official patch is available from the vendor.
