USN-5693-1: Linux kernel (OEM) vulnerabilities<\/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 denial
\nof service (system crash) or possibly execute arbitrary code.
\n(CVE-2022-2602)<\/p>\n
Duoming Zhou discovered that race conditions existed in the timer handling
\nimplementation of the Linux kernel’s Rose X.25 protocol layer, resulting in
\nuse-after-free vulnerabilities. A local attacker could use this to cause a
\ndenial of service (system crash). (CVE-2022-2318)<\/p>\n
Hao Sun and Jiacheng Xu discovered that the NILFS file system
\nimplementation in the Linux kernel contained a use-after-free
\nvulnerability. A local attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2022-2978)<\/p>\n
Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in
\nthe Linux kernel. A local attacker could use this to cause a denial of
\nservice (system crash) or possibly expose sensitive information (kernel
\nmemory). (CVE-2022-3028)<\/p>\n
Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX
\nstorage controller driver in the Linux kernel did not properly handle
\ncertain structures. A local attacker could potentially use this to expose
\nsensitive information (kernel memory). (CVE-2022-40768)<\/p>\n
S\u00f6nke Huster discovered that an integer overflow vulnerability existed in
\nthe WiFi driver stack in the Linux kernel, leading to a buffer overflow. A
\nphysically proximate attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2022-41674)<\/p>\n
S\u00f6nke Huster discovered that a use-after-free vulnerability existed in the
\nWiFi driver stack in the Linux kernel. A physically proximate attacker
\ncould use this to cause a denial of service (system crash) or possibly
\nexecute arbitrary code. (CVE-2022-42719)<\/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
