{"id":"OESA-2023-1764","summary":"kernel security update","details":"The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nA flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.(CVE-2023-39192)\r\n\r\nA NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system.(CVE-2023-42754)\r\n\r\nAn issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for frames larger than the MTU.(CVE-2023-45871)","modified":"2026-03-11T06:34:24.802939Z","published":"2023-10-27T11:06:10Z","upstream":["CVE-2023-39192","CVE-2023-42754","CVE-2023-45871"],"database_specific":{"severity":"Critical"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2023-1764"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-39192"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-42754"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45871"}],"affected":[{"package":{"name":"kernel","ecosystem":"openEuler:20.03-LTS-SP3","purl":"pkg:rpm/openEuler/kernel&distro=openEuler-20.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.19.90-2310.4.0.0223.oe1"}]}],"ecosystem_specific":{"x86_64":["python3-perf-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","bpftool-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","python2-perf-debuginfo-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","python2-perf-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-debugsource-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","perf-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","bpftool-debuginfo-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-tools-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-tools-devel-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","python3-perf-debuginfo-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-devel-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-debuginfo-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-source-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","kernel-tools-debuginfo-4.19.90-2310.4.0.0223.oe1.x86_64.rpm","perf-debuginfo-4.19.90-2310.4.0.0223.oe1.x86_64.rpm"],"src":["kernel-4.19.90-2310.4.0.0223.oe1.src.rpm"],"aarch64":["perf-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-tools-debuginfo-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","bpftool-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","python3-perf-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-source-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-debugsource-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-debuginfo-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","python2-perf-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","bpftool-debuginfo-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","python2-perf-debuginfo-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-devel-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","python3-perf-debuginfo-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-tools-devel-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","perf-debuginfo-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-4.19.90-2310.4.0.0223.oe1.aarch64.rpm","kernel-tools-4.19.90-2310.4.0.0223.oe1.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2023-1764.json"}}],"schema_version":"1.7.5"}
