Overview
CVE-2026-98828 is a known-severity vulnerability. It was published on October 18, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: reject short WMI command responses
ath9k_wmi_rsp_callback() removes the validated WMI header and copies
the number of bytes expected by the waiting command into its response
buffer. A device response shorter than that expectation can therefore
be read beyond the skb payload.
Record -EMSGSIZE for a short response, complete the waiter, and return
the stored status from the command path. This also prevents callers from
consuming stale response bytes as a successful reply.

How can CyberStrike help with CVE-2026-98828?
CyberStrike is an open-source, AI-augmented pentesting engine.
