LSN-0090-1: Kernel Live Patch Security Notice<\/p>\n
David Bouman discovered that the netfilter subsystem in the Linux kernel
\ndid not properly validate passed user register indices. A local attacker
\ncould use this to cause a denial of service or possibly execute
\narbitrary code. (CVE-2022-1015)<\/p>\n
David Bouman and Billy Jheng Bing Jhong discovered that a race condition
\nexisted in the io_uring subsystem in the Linux kernel, leading to a use-
\nafter-free vulnerability. A local attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.(CVE-2022-2602)<\/p>\n
S\u00f6nke Huster discovered that an integer overflow vulnerability existed
\nin the WiFi driver stack in the Linux kernel, leading to a buffer
\noverflow. A physically proximate attacker could use this to cause an
\ndenial of service (system crash) or possibly execute arbitrary code.(CVE-2022-41674)<\/p>\n
S\u00f6nke Huster discovered that the WiFi driver stack in the Linux kernel did
\nnot properly perform reference counting in some situations, leading to a
\nuse-after-free vulnerability. A physically proximate attacker could use
\nthis to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2022-42720)<\/p>\n
S\u00f6nke Huster discovered that the WiFi driver stack in the Linux kernel did
\nnot properly handle BSSID\/SSID lists in some situations. A physically
\nproximate attacker could use this to cause a denial of service (infinite
\nloop). (CVE-2022-42721)<\/p>\n
