Descriptions

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()

Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug
occurs when txs->cnt, data from a URB provided by a USB device, is
bigger than the size of the array txs->txstatus, which is
HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug
handling code after the check. Make the function return if that is the
case.

Found by a modified version of syzkaller.

UBSAN: array-index-out-of-bounds in htc_drv_txrx.c
index 13 is out of range for type '__wmi_event_txstatus [12]'
Call Trace:

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath9k: corrige una posible lectura de índice de matriz fuera de los límites en ath9k_htc_txstatus(). Corrige una lectura de índice de matriz fuera de los límites en ath9k_htc_txstatus(). El error ocurre cuando txs->cnt, los datos de una URB proporcionados por un dispositivo USB, son mayores que el tamaño de la matriz txs->txstatus, que es HTC_MAX_TX_STATUS. WARN_ON() ya lo verifica, pero no hay ningún código de manejo de errores después de la verificación. Haga que la función regrese si ese es el caso. Encontrado por una versión modificada de syzkaller. UBSAN: Array-Index-Of-Bunds en htc_drv_txrx.c El índice 13 está fuera de rango para el tipo '__WMI_EVENT_TXSTATUS [12]' LLAME TRACE: ATH9K_HTC_TXSTATUS ATH9K_WMI_EVENT_TASKLET_ACTION_ACTION_COMNOMON __DO_SOFTIRQ IRQITITI

A potential array-index-out-of-bounds read flaw was found in the Linux kernel in ath9k_htc_txstatus(). This issue may lead to a crash.
