漏洞标题
无线网络: mac80211: 不清除未上传的站表项
来源:AIGC 神龙大模型
漏洞描述信息
在Linux内核中,已解决了以下漏洞: wifi: mac80211: 不清除未上传的STA 如果STA状态提前被移到AUTHORIZED(如在IBSS场景中),并且插入失败,该站会被释放。在这种情况下,驱动程序从未了解过该站,因此试图清除它是意外的,可能会导致崩溃。 检查STA是否之前已上传到驱动程序并修复此问题。

wifi: mac80211: don't flush non-uploaded STAs
来源:美国国家漏洞数据库 NVD
漏洞描述信息
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't flush non-uploaded STAs If STA state is pre-moved to AUTHORIZED (such as in IBSS scenarios) and insertion fails, the station is freed. In this case, the driver never knew about the station, so trying to flush it is unexpected and may crash. Check if the sta was uploaded to the driver before and fix this.
