Description

Kernel Live Patch Security Notice David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-1015) David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2022-2602) 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 an denial of service (system crash) or possibly execute arbitrary code.(CVE-2022-41674) 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). (CVE-2022-42722)
