{"id":"USN-6573-1","summary":"linux-azure vulnerabilities","details":"Lucas Leong discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate some attributes passed from userspace. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly expose sensitive information (kernel memory). (CVE-2023-39189)\n\nKyle Zeng discovered that the IPv4 implementation in the Linux kernel did\nnot properly handle socket buffers (skb) when performing IP routing in\ncertain circumstances, leading to a null pointer dereference vulnerability.\nA privileged attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-42754)\n\nYikebaer Aizezi discovered that the ext4 file system implementation in the\nLinux kernel contained a use-after-free vulnerability when handling inode\nextent metadata. An attacker could use this to construct a malicious ext4\nfile system image that, when mounted, could cause a denial of service\n(system crash). (CVE-2023-45898)\n\nJason Wang discovered that the virtio ring implementation in the Linux\nkernel did not properly handle iov buffers in some situations. A local\nattacker in a guest VM could use this to cause a denial of service (host\nsystem crash). (CVE-2023-5158)\n\nAlon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel\ndid not properly handle queue initialization failures in certain\nsituations, leading to a use-after-free vulnerability. A remote attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-5178)\n\nBudimir Markovic discovered that the perf subsystem in the Linux kernel did\nnot properly handle event groups, leading to an out-of-bounds write\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-5717)\n\n","modified":"2026-02-04T04:09:25.220535Z","published":"2024-01-09T18:30:25.533244Z","related":["CVE-2023-39189","CVE-2023-42754","CVE-2023-45898","CVE-2023-5158","CVE-2023-5178","CVE-2023-5717","UBUNTU-CVE-2023-39189","UBUNTU-CVE-2023-42754","UBUNTU-CVE-2023-45898","UBUNTU-CVE-2023-5158","UBUNTU-CVE-2023-5178","UBUNTU-CVE-2023-5717"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6573-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-5158"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-5178"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-5717"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-39189"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-42754"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-45898"}],"affected":[{"package":{"name":"linux-azure","ecosystem":"Ubuntu:23.10","purl":"pkg:deb/ubuntu/linux-azure@6.5.0-1010.10?arch=source&distro=mantic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.5.0-1010.10"}]}],"versions":["6.2.0-1003.3","6.2.0-1004.4","6.5.0-1004.4","6.5.0-1006.6","6.5.0-1007.7","6.5.0-1008.8","6.5.0-1009.9"],"ecosystem_specific":{"binaries":[{"binary_version":"6.5.0-1010.10","binary_name":"linux-azure-cloud-tools-6.5.0-1010"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-azure-headers-6.5.0-1010"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-azure-tools-6.5.0-1010"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-buildinfo-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-cloud-tools-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-headers-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-image-unsigned-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-image-unsigned-6.5.0-1010-azure-dbgsym"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-modules-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-modules-extra-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-modules-iwlwifi-6.5.0-1010-azure"},{"binary_version":"6.5.0-1010.10","binary_name":"linux-tools-6.5.0-1010-azure"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-6573-1.json"}}],"schema_version":"1.7.3"}
