Description OSIDB Bzimport 2025-02-26 03:07:41 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ath9k_htc: fix potential out of bounds access with invalid rxstatus->rs_keyix

The "rxstatus->rs_keyix" eventually gets passed to test_bit() so we need to
ensure that it is within the bitmap.

drivers/net/wireless/ath/ath9k/common.c:46 ath9k_cmn_rx_accept()
error: passing untrusted data 'rx_stats->rs_keyix' to 'test_bit()'
