Probably the most important vulnerability addressed by the new kernel live patch for Ubuntu Linux is CVE-2019-14615, a flaw affecting certain Intel graphics processors. This could allow a local attacker to expose sensitive information. The new kernel live patch addresses several heap-based buffer overflow vulnerabilities discovered in Linux kernel’s Marvell WiFi-Ex driver (CVE-2019-14895 and CVE-2019-14901) and Marvell Libertas WLAN driver (CVE-2019-14896 and CVE-2019-14897). These flaws could allow physically proximate attackers to cause a system crash or execute arbitrary code.
