There can be a use-after-free in the packet processing context, because the per-CPU sequence count is mishandled during concurrent iptables rules replacement. This could be exploited with the CAP_NET_ADMIN capability in an unprivileged namespace. NOTE: cc00bca was reverted in 5.12.(CVE-2020-36694)\n\nA use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service (DoS) or a kernel information leak.(CVE-2022-1280)","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":"4.19.90-2305.4.0.0203.oe1"}]}],"ecosystem_specific":{"aarch64":["bpftool-debuginfo-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","python2-perf-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-devel-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-debuginfo-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-source-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","perf-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","python3-perf-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-tools-devel-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-tools-debuginfo-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-debugsource-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","bpftool-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","perf-debuginfo-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","kernel-tools-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","python3-perf-debuginfo-4.19.90-2305.4.0.0203.oe1.aarch64.rpm","python2-perf-debuginfo-4.19.90-2305.4.0.0203.oe1.aarch64.rpm"],"src":["kernel-4.19.90-2305.4.0.0203.oe1.src.rpm"],"x86_64":["kernel-source-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-debugsource-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-devel-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","bpftool-debuginfo-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-debuginfo-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","python3-perf-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","python2-perf-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-tools-devel-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","python2-perf-debuginfo-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","bpftool-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","perf-debuginfo-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-tools-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","kernel-tools-debuginfo-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","python3-perf-debuginfo-4.19.90-2305.4.0.0203.oe1.x86_64.rpm","perf-4.19.90-2305.4.0.0203.oe1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2023-1303"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36694"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-1280"}],"database_specific":{"severity":"Critical"}}
