Description

linux, linux-aws, linux-gcp, linux-gcp-5.3, linux-hwe, linux-kvm, linux-oracle, linux-oracle-5.3, linux-raspi2, linux-raspi2-5.3 vulnerabilities It was discovered that the IPMI message handler implementation in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19046) Al Viro discovered that the vfs layer in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2020-8428)
