What the advisory describes
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix potential buffer underflow in ath11k_hal_rx_msdu_list_get() When the first entry in msdu_details has a zero buffer address, the code accesses msdu_details[i - 1] with i == 0, causing a buffer underflow. Fix similarly to ath12k_wifi7_hal_rx_msdu_list_get() by adding a separate check for i == 0 before the main condition to prevent the out-of-bounds access. Found by Linux Verification Center (linuxtesting.org) with SVACE.
Source: EUVD (ENISA), in the words of the advisory.
