Exploitation requires the attacker to be in a privileged adjacent network position - either directly connected to the same Wi-Fi network or capable of injecting crafted frames into the wireless medium, typically requiring specialized Wi-Fi equipment (packet injection capability). The attack does not require authentication or user interaction (PR:N, UI:N). However, exploitation has high attack complexity (AC:H), meaning specific radio conditions, device state, or frame sequencing must be precisely met to trigger the use-after-free - generic frame injection will not reliably trigger the flaw. Devices in airplane mode or with Wi-Fi disabled are not vulnerable.

This vulnerability presents low real-world risk despite being patched. The EPSS score of 0.02% (7th percentile) indicates extremely low exploitation probability in the wild, suggesting attackers have not widely weaponized this flaw. While CVSS 5.3 appears moderate, the contributing factors significantly limit practical risk: AV:A restricts attacks to adjacent network attackers; AC:H indicates attack complexity is high, requiring specific conditions (likely radio environment, frame timing, or device state); UI:N and PR:N mean no user interaction is needed once conditions are met. The impact is limited to availability (denial-of-service only) - no confidentiality or integrity compromise. The lack of KEV listing and zero identified public exploits further confirm this remains a low-priority vulnerability outside targeted scenarios against high-value targets on controlled networks. Organizations should prioritize patching based on deployment risk (if Wi-Fi-exposed), not on perceived CVSS severity.

An attacker positioned on the same Wi-Fi network (or with wireless injection capability) crafts a series of malicious Wi-Fi frames targeting the device's Wi-Fi driver. The frames trigger a use-after-free condition in the packet processing logic, causing memory corruption. The device's Wi-Fi stack crashes or becomes unresponsive, resulting in loss of network connectivity and potential system instability. This scenario requires the attacker to be adjacent to the target (same network or radio range) and to have reverse-engineered the exact packet format and timing to trigger the high-complexity exploitation condition.
