A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%.(CVE-2023-1206)\r\n\r\nA buffer overrun vulnerability was found in the netback driver in Xen due to an unusual split packet. This flaw allows an unprivileged guest to cause a denial of service (DoS) of the host by sending network packets to the backend, causing the backend to crash.(CVE-2023-34319)\r\n\r\nAn issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.(CVE-2023-40283)\r\n\r\nA flaw was found in the Linux kernel\u0026apos;s TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 (\u0026quot;tun: tun_chr_open(): correctly initialize socket uid\u0026quot;), - 66b2c338adce (\u0026quot;tap: tap_open(): correctly initialize socket uid\u0026quot;), pass \u0026quot;inode-\u0026gt;i_uid\u0026quot; to sock_init_data_uid() as the last parameter and that turns out to not be accurate.(CVE-2023-4194)\r\n\r\nA NULL pointer dereference flaw was found in dbFree in fs/jfs/jfs_dmap.c in the journaling file system (JFS) in the Linux Kernel. This issue may allow a local attacker to crash the system due to a missing sanity check.(CVE-2023-4385)\r\n\r\nA NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with normal user privilege to cause a denial of service due to a missing sanity check during cleanup.(CVE-2023-4459)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP1","name":"kernel","purl":"pkg:rpm/openEuler/kernel\u0026distro=openEuler-20.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.19.90-2308.5.0.0216.oe1"}]}],"ecosystem_specific":{"aarch64":["kernel-debuginfo-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-debugsource-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","bpftool-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","python2-perf-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","bpftool-debuginfo-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","python3-perf-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-tools-devel-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","perf-debuginfo-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","python3-perf-debuginfo-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","python2-perf-debuginfo-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-tools-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","perf-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-tools-debuginfo-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-devel-4.19.90-2308.5.0.0216.oe1.aarch64.rpm","kernel-source-4.19.90-2308.5.0.0216.oe1.aarch64.rpm"],"src":["kernel-4.19.90-2308.5.0.0216.oe1.src.rpm"],"x86_64":["kernel-source-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-tools-devel-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","python2-perf-debuginfo-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","bpftool-debuginfo-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-tools-debuginfo-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-tools-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","python2-perf-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","bpftool-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-devel-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","python3-perf-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","perf-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","python3-perf-debuginfo-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","perf-debuginfo-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-debugsource-4.19.90-2308.5.0.0216.oe1.x86_64.rpm","kernel-debuginfo-4.19.90-2308.5.0.0216.oe1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2023-1588"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-1206"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34319"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-40283"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-4194"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-4385"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-4459"}],"database_specific":{"severity":"High"}}
