Description

A flaw was found in the Linux kernel's ath5k Wi-Fi driver. This vulnerability allows for an array-index-out-of-bounds write in the `ath5k_tasklet_tx` function. An attacker could potentially trigger this by manipulating specific index values, leading to a minor data corruption. The immediate impact of this out-of-bounds write is considered negligible, affecting only the `ack_signal` member of the `info->status` structure.
