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 [ more… ]
