USN-5518-1

Summary: linux, linux-aws, linux-azure, linux-gcp, linux-gke, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi vulnerabilities

Details: It was discovered that the eBPF implementation in the Linux kernel did not properly prevent writes to kernel objects in BPF_BTF_LOAD commands. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-0500) It was discovered that the Marvell NFC device driver implementation in the Linux kernel did not properly perform memory cleanup operations in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1734) Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1789) Duoming Zhou discovered a race condition in the NFC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1974) Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not properly prevent context switches from occurring during certain atomic context operations. A privileged local attacker could use this to cause a denial of service (system crash). (CVE-2022-1975) Minh Yuan discovered that the floppy driver in the Linux kernel contained a race condition in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-33981)
