In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: Add missing hw_ops->get_ring_selector() for IPQ5018. During data transmission after client connections, the hw_ops->get_ring_selector() will be called. However, for IPQ5018, this member isn't set, resulting in a NULL pointer exception.
This vulnerability allows attackers to potentially disrupt service due to a kernel NULL pointer dereference, which could lead to system crashes or instability. Although classified as low risk in terms of exploitability, organizations are advised to remain vigilant.
Given the nature of this vulnerability and its deferred status, it is essential for organizations to prioritize patching the affected systems once a resolution is available.
This vulnerability was published on December 24, 2025, and organizations should incorporate it into their vulnerability management programs to ensure timely remediation.
