A local\nattacker could use this to cause a denial of service (system crash) or\nexecute arbitrary code (CVE-2021-3491).\n\nAn out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in\nthe f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds\ncheck failure allows a local attacker to gain access to out-of-bounds\nmemory leading to a system crash or a leak of internal kernel information\n(CVE-2021-3506).\n\nA race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before\n5.12-rc8 can lead to kernel privilege escalation from the context of a\nnetwork service or an unprivileged process. If sctp_destroy_sock is called\nwithout sock_net(sk)->sctp.addr_wq_lock then an element is removed from\nthe auto_asconf_splist list without any proper locking. This can be\nexploited by an attacker with network service privileges to escalate to\nroot or from the context of an unprivileged user directly if a\nBPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some\nSCTP socket. \nNOTE! This already had a fix in kernel-5.10.33, but that fix caused some\nsystems to deadlock, so this is now fixed in a better way (CVE-2021-23133).\n\nbpf: Fix propagation of 32 bit unsigned bounds from 64 bit bounds\n(CVE-2021-31440).\n\nkernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable\nspeculative loads, leading to disclosure of stack content via side-channel\nattacks. The specific concern is not protecting the BPF stack area against\nspeculative loads. Also, the BPF stack can contain uninitialized data that\nmight represent sensitive information previously operated on by the kernel\n(CVE-2021-31829).\n\nnet/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race\ncondition for removal of the HCI controller (CVE-2021-32399).\n\nIn the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a\nuse-after-free when destroying an hci_chan. This leads to writing an\narbitrary value. (CVE-2021-33034).\n\nFor other upstream fixes, see the referenced changelogs.\n",null,[],[],[],[14,16,18,20,22,24,26],{"_key":15},"CVE-2021-23133",{"_key":17},"CVE-2021-31440",{"_key":19},"CVE-2021-31829",{"_key":21},"CVE-2021-32399",{"_key":23},"CVE-2021-33034",{"_key":25},"CVE-2021-3491",{"_key":27},"CVE-2021-3506",[],[],[31,32,33,34,35,36,37],{"_key":15},{"_key":17},{"_key":19},{"_key":21},{"_key":23},{"_key":25},{"_key":27},"2021-05-19T19:29:59Z","2026-04-16T04:41:26.250898979Z",{"cisa_kev":41,"cisa_ransomware":41,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[43,49,54,59,63,67],{"url":44,"sources":45,"tags":47},"https://advisories.mageia.org/MGASA-2021-0215.html",[46],"osv_mageia",[48],"Advisory",{"url":50,"sources":51,"tags":52},"https://bugs.mageia.org/show_bug.cgi?id=28917",[46],[53],"REPORT",{"url":55,"sources":56,"tags":57},"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10.34",[46],[53,58],"WEB",{"url":60,"sources":61,"tags":62},"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10.35",[46],[53,58],{"url":64,"sources":65,"tags":66},"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10.36",[46],[53,58],{"url":68,"sources":69,"tags":70},"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10.37",[46],[53,58],[],[],[],[75,87],{"ecosystem":76,"name":77,"vendor":78,"product":77,"cpe_part":9,"purl_type":79,"purl_namespace":78,"purl_name":77,"source":9,"versions":80},"Mageia","kernel-linus","mageia","rpm",[81],{"version":82,"is_range":83,"range_type":84,"version_start":9,"version_start_type":9,"version_end":85,"version_end_type":86,"fixed_in":9},"lt5_10_37_1_mga7",true,"ecosystem","5.10.37-1.mga7","excluding",{"ecosystem":76,"name":77,"vendor":78,"product":77,"cpe_part":9,"purl_type":79,"purl_namespace":78,"purl_name":77,"source":9,"versions":88},[89],{"version":90,"is_range":83,"range_type":84,"version_start":9,"version_start_type":9,"version_end":91,"version_end_type":86,"fixed_in":9},"lt5_10_37_1_mga8","5.10.37-1.mga8"]
