CVE-2026-98830

The Linux kernel contains a vulnerability in the wifi: wfx component. The function wfx_hif_read_mib() fails to validate that the reply->length from a firmware response does not exceed the val_len of the caller-provided buffer. This lack of bounds checking allows a firmware response with an ove...

CVE-2026-98829

The Linux kernel contains a vulnerability in the mac80211 component where oversized fragments can cause an extra_len overflow . The root cause is that entry->extra_len was narrowed from unsigned int to u16 to reduce memory footprint. When a sequence of large fragments exceeds 65535 bytes, the ...

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: reject short WMI command responses ath9kwmirspcallback 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...

CVE-2026-98828

The Linux kernel contains a vulnerability in the ath9k wifi driver within the ath9k_wmi_rsp_callback() function. The root cause is that the function copies the number of bytes expected by a waiting command into a response buffer without sufficiently verifying the length of the device response. If...
