Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An array-index-out-of-bounds access exists in the ath5k WiFi driver. The issue occurs within the
ath5k tasklet tx() function in the drivers/net/wireless/ath/ath5k/base.c file. Specifically, the driver may attempt to access an index beyond the defined size of the ieee80211 tx rate array, which has a maximum size of 4 (IEEE80211 TX MAX RATES). This happens when ts->ts final idx is 3, causing the operation info->status.rates[ts->ts final idx + 1].idx = -1 to write outside the array boundaries, overwriting the ack signal member of info->status.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
