{"id":"LSN-0069-1","summary":"Kernel Live Patch Security Notice","details":"Relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local\nusers to cause a denial of service (such as relay blockage) by triggering a\nNULL alloc_percpu result. (CVE-2019-19462)\n\nFan Yang discovered that the mremap implementation in the Linux kernel did\nnot properly handle DAX Huge Pages. A local attacker with access to DAX\nstorage could use this to gain administrative privileges. (CVE-2020-10757)\n\nIt was discovered that the DesignWare SPI controller driver in the Linux\nkernel contained a race condition. A local attacker could possibly use this\nto cause a denial of service (system crash). (CVE-2020-12769)\n\nIn the Linux kernel before 5.4.16, a race condition in tty-\u003edisc_data\nhandling in the slip and slcan line discipline could lead to a\nuse-after-free, aka CID-0ace17d56824.
