{"id":"USN-5727-2","summary":"linux-gcp, linux-gcp-4.15  vulnerabilities","details":"It was discovered that a race condition existed in the instruction emulator\nof the Linux kernel on Arm 64-bit systems. A local attacker could use this\nto cause a denial of service (system crash). (CVE-2022-20422)\n\nIt was discovered that the KVM implementation in the Linux kernel did not\nproperly handle virtual CPUs without APICs in certain situations. A local\nattacker could possibly use this to cause a denial of service (host system\ncrash). (CVE-2022-2153)\n\nHao 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)\n\nAbhishek 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)\n\nIt was discovered that the IDT 77252 ATM PCI device driver in the Linux\nkernel did not properly remove any pending timers during device exit,\nresulting in a use-after-free vulnerability. A local attacker could\npossibly use this to cause a denial of service (system crash) or execute\narbitrary code. (CVE-2022-3635)\n\nIt was discovered that the Netlink Transformation (XFRM) subsystem in the\nLinux kernel contained a reference counting error. A local attacker could\nuse this to cause a denial of service (system crash). (CVE-2022-36879)\n\nXingyuan 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).
