CVE-2023-52594

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a potential array-index-out-of-bounds read in the ath9k htc txstatus() function. This 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. Although WARN ON() checks for this condition, there is no bug handling code after the check. The function will now return if this condition is met. The bug was found by a modified version of syzkaller and is associated with an array-index-out-of-bounds error in htc drv txrx.c, where index 13 is out of range for type ' wmi event txstatus [12]'. The call trace includes ath9k htc txstatus, ath9k wmi event tasklet, tasklet action common, do softirq, irq exit rxu, and sysvec apic timer interrupt.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
