It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1076) It was discovered that the Real-Time Scheduling Class implementation in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1077) It was discovered that the ASUS HID driver in the Linux kernel did not properly handle device removal, leading to a use-after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash). (CVE-2023-1079) It was discovered that the Xircom PCMCIA network device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1670) It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2023-1859) Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were insufficient in some situations.
