This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.","state":0,"publishedAt":"2020-09-16T00:00:00+00:00","modifiedAt":"2026-10-08T21:03:17.359+00:00","affected":[{"ecosystem":"Vendor product","name":"kernel","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Linux Kernel\",\n                    \"product\": \"kernel\",\n                    \"versions\": [\n                        {\n                            \"version\": \"before 5.8-rc6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5,"severity":"MEDIUM"}],"references":["https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=853eab68afc80f59f36bbdeb715e5c88c501e680","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10781","https://www.openwall.com/lists/oss-security/2020/06/18/1","https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2020-10781","license":"CVE Program Terms of Use","key":"cve-program:CVE-2020-10781","identifiers":["CVE-2020-10781"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
