In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: fix use-after-free bugs in mt7996_mac_dump_work() When the mt7996 pci chip is detaching, the mt7996_crash_data is released in mt7996_coredump_unregister(). However, the work item dump_work may still be running or pending, leading to UAF bugs when the already freed crash_data is dereferenced again in mt7996_mac_dump_work(). The race condition can occur as follows: CPU 0 (removal path) | CPU 1 (workqueue) mt7996_pci_remove() | mt7996_sys_recovery_set() mt7996_unregister_device() | mt7996_reset() mt7996_coredump_unregister() | queue_work() vfree(dev->coredump.crash_data) | mt7996_mac_dump_work() | crash_data-> // UAF Fix this by ensuring dump_work is properly canceled before the crash_data is deallocated. Add cancel_work_sync() in mt7996_unregister_device() to synchronize with any pending or executing dump work.
AI Analysis
Technical Summary
This vulnerability involves use-after-free bugs in the mt7996_mac_dump_work() function of the mt76 WiFi driver component in Microsoft software version 3.0. Use-after-free vulnerabilities can lead to memory corruption, potentially allowing an attacker to cause a denial of service or execute arbitrary code, but no specific impact details or exploitation methods are provided in the available data.
Potential Impact
The impact is not explicitly detailed in the provided information. Use-after-free bugs generally risk memory corruption, which could lead to system instability or potential code execution. However, no known exploits or confirmed impact scenarios are reported.
Mitigation Recommendations
