No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，以下漏洞已得到修复： wifi: mt76: mt7915: 在 add_interface 失败时执行状态回滚（unwind） 当 失败时， 在返回前未清除它此前已设置的 / 位，未移除之前添加的固件设备信息，也未清除指向即将由 mac80211 释放的 指针。由于 mac80211 在 add 操作失败时不会调用 ，因此相关的索引和固件设备条目会永久泄漏，并且 testmode 可能解引用这个过时的 指针。现添加了正确的错误回滚逻辑。

Vulnerability Title
wifi: mt76: mt7915: unwind state on add_interface failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: unwind state on add_interface failure
When mt76_wcid_alloc() fails, mt7915_add_interface() returned without
clearing the vif_mask/omac_mask bits it had already set, without removing
the firmware dev info added earlier, and without clearing a monitor_vif
pointer to the vif mac80211 is about to free. mac80211 does not call
remove_interface() for a failed add, so the indices and firmware dev
entry leaked permanently and testmode could dereference the stale
monitor_vif. Add a proper error unwind.
