CVE-2026-92496 in Linux
要約
〜によって MITRE • 2026年09月17日
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Avoid buffer overread in ath11k_wmi_tlv_op_rx()
Currently, in ath11k_wmi_tlv_op_rx(), the firmware buffer is read without first verifying that the buffer has enough data to hold a header. This could result in a buffer overread.
Add an upfront length check before dereferencing skb->data as a wmi_cmd_hdr. The check is placed before the trace_ath11k_wmi_event() call to preserve the existing trace semantics (tracing the full raw WMI event including the header), unlike the analogous ath12k fix which could use skb_pull_data() directly.
Compile tested only.
