In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: 8822b: Avoid WARNING in rtw8822b_config_trx_mode() rtw8822b_set_antenna() can be called from userspace when the chip is powered off. In that case a WARNING is triggered in rtw8822b_config_trx_mode() because trying to read the RF registers when the chip is powered off returns an unexpected value. Call rtw8822b_config_trx_mode() in rtw8822b_set_antenna() only when the chip is powered on. ------------[ cut here ]------------ write RF mode table fail WARNING: CPU: 0 PID: 7183 at rtw8822b.c:824 rtw8822b_config_trx_mode.constprop.0+0x835/0x840 [rtw88_8822b] CPU: 0 UID: 0 PID: 7183 Comm: iw Tainted: G W OE 6.17.5-arch1-1 #1 PREEMPT(full) 01c39fc421df2af799dd5e9180b572af860b40c1 Tainted: [W]=WARN, [O]=OOT_MODULE, [E]=UNSIGNED_MODULE Hardware name: LENOVO 82KR/LNVNB161216, BIOS HBCN18WW 08/27/2021 RIP: 0010:rtw8822b_config_trx_mode.constprop.0+0x835/0x840 [rtw88_8822b] Call Trace: rtw8822b_set_antenna+0x57/0x70 [rtw88_8822b 370206f42e5890d8d5f48eb358b759efa37c422b] rtw_ops_set_antenna+0x50/0x80 [rtw88_core 711c8fb4f686162be4625b1d0b8e8c6a5ac850fb] ieee80211_set_antenna+0x60/0x100 [mac80211 f1845d85d2ecacf3b71867635a050ece90486cf3] nl80211_set_wiphy+0x384/0xe00 [cfg80211 296485ee85696d2150309a6d21a7fbca83d3dbda] ? netdev_run_todo+0x63/0x550 genl_family_rcv_msg_doit+0xfc/0x160 genl_rcv_msg+0x1aa/0x2b0 ? __pfx_nl80211_pre_doit+0x10/0x10 [cfg80211 296485ee85696d2150309a6d21a7fbca83d3dbda] ? __pfx_nl80211_set_wiphy+0x10/0x10 [cfg80211 296485ee85696d2150309a6d21a7fbca83d3dbda] ? __pfx_nl80211_post_doit+0x10/0x10 [cfg80211 296485ee85696d2150309a6d21a7fbca83d3dbda] ? __pfx_genl_rcv_msg+0x10/0x10 netlink_rcv_skb+0x59/0x110 genl_rcv+0x28/0x40 netlink_unicast+0x285/0x3c0 ? __alloc_skb+0xdb/0x1a0 netlink_sendmsg+0x20d/0x430 ____sys_sendmsg+0x39f/0x3d0 ? import_iovec+0x2f/0x40 ___sys_sendmsg+0x99/0xe0 ? refill_obj_stock+0x12e/0x240 __sys_sendmsg+0x8a/0xf0 do_syscall_64+0x81/0x970 ? do_syscall_64+0x81/0x970 ?

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2025-71297 is a medium public vulnerability record for linux linux kernel. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether linux linux kernel is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: linux/linux kernel. Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: CVSS 5.5, EPSS 0.1%. It is not currently listed in the CISA Known Exploited catalog. Sources contributing to this record: cve_org, epss, nvd. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.

Exploitation and remediation

  • Exploitation evidence
