CVE-2026-98827 wifi: ath9k_htc: bound TX aggregation to MAX_TX_BUF_SIZE

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9khtc: bound TX aggregation to MAXTXBUFSIZE hifusbtx dequeues up to MAXTXAGGRNUM 20 frames into a single txbuf of MAXTXBUFSIZE 32768 bytes, limiting the batch by record count but never by cumulative byte length. With lar...

CVE-2026-98827

The Linux kernel contains a vulnerability in the wifi: ath9k_htc driver where the __hif_usb_tx() function fails to check the cumulative byte length of aggregated frames. While the function limits the batch by record count (MAX_TX_AGGR_NUM), large frames with an MTU of 2304 can exceed the MAX_TX_B...
