{"id":"DEBIAN-CVE-2023-54300","details":"In the Linux kernel, the following vulnerability has been resolved:  wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rx  For the reasons also described in commit b383e8abed41 (\"wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg()\"), ath9k_htc_rx_msg() should validate pkt_len before accessing the SKB.  For example, the obtained SKB may have been badly constructed with pkt_len = 8. In this case, the SKB can only contain a valid htc_frame_hdr but after being processed in ath9k_htc_rx_msg() and passed to ath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMI command header which should be located inside its data payload.  Implement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninit memory can be referenced.  Tested on Qualcomm Atheros Communications AR9271 802.11n .  Found by Linux Verification Center (linuxtesting.org) with Syzkaller.","modified":"2026-09-15T08:47:47.639943155Z","published":"2025-12-30T13:16:19.120Z","upstream":["CVE-2023-54300"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54300"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.52-1"}]}],"versions":["6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54300.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.4.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54300.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.4.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54300.json"}}],"schema_version":"1.9.0"}
