Description

linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-gcp, linux-gcp-5.4, linux-gke, linux-gkeop, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4, linux-xilinx-zynqmp vulnerabilities It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3090) Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-32629) It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error conditions, 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-2023-3390) Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain pointer data type, leading to an out-of- bounds write vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35001)
