USN-4346-1 Not scored

linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon vulnerabilities

It was discovered that the QLogic Fibre Channel driver in the Linux kernel did not properly check for error, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16233) It was discovered that the Intel Wi-Fi driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16234) Tristan Madani discovered that the block I/O tracing implementation in the Linux kernel contained a race condition. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-19768) It was discovered that the virtual terminal implementation in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2020-8648) Jordy Zomer discovered that the floppy driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-9383)
