Sönke Huster discovered that an integer overflow vulnerability existed in
the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-41674)
Sönke Huster discovered that a use-after-free vulnerability existed in the
WiFi driver stack in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-42719)
Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly perform reference counting in some situations, leading to a
use-after-free vulnerability. A physically proximate attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2022-42720)
Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly handle BSSID/SSID lists in some situations. A physically
proximate attacker could use this to cause a denial of service (infinite
loop). (CVE-2022-42721)
Sönke Huster discovered that the WiFi driver stack in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
physically proximate attacker could use this to cause a denial of service
(system crash). This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.10.
