Description

linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities It was discovered that the LIO SCSI target implementation in the Linux kernel performed insufficient identifier checking in certain XCOPY requests. An attacker with access to at least one LUN in a multiple backstore environment could use this to expose sensitive information or modify data. (CVE-2020-28374) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track inode validations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service (system crash). (CVE-2018-13093) It was discovered that the btrfs file system implementation in the Linux kernel did not properly validate file system metadata in some situations. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service (system crash). (CVE-2019-19813, CVE-2019-19816) Bodong Zhao discovered a use-after-free in the Sun keyboard driver implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2020-25669)
