{"schema":"threatline.record/2","record":{"id":"CVE-2026-98936","aliases":[],"summary":"wifi: ath11k: reset ar->num_stations on hardware start","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath11k: reset ar->num_stations on hardware start\n\nWhen (multiple) hw restart occurs, we end up in a situation where we\ncannot accept new stations / mesh peers. This seems to be the\n'num_stations' in 'struct ath11k' that did not get reset properly in\nthis case. In ath11k_mac_op_start(), it was indeed the only accounting var\nthat did not get reset so let's clear it too.\n\nThis avoids problems like those:\n\n\t[1248828.088023] WARNING: CPU: 0 PID: 12281 at
