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."}],"affected":[{"vendor":"Linux Kernel","product":"kernel","versions":[{"version":"before 5.8-rc6","status":"affected"}]}],"references":[{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=853eab68afc80f59f36bbdeb715e5c88c501e680"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10781"},{"url":"https://www.openwall.com/lists/oss-security/2020/06/18/1"},{"name":"[debian-lts-announce] 20200928 [SECURITY] [DLA 2385-1] linux-4.19 security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":5.5,"baseSeverity":"MEDIUM"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-732","cweId":"CWE-732"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-04T11:14:15.582Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=853eab68afc80f59f36bbdeb715e5c88c501e680","tags":["x_transferred"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10781","tags":["x_transferred"]},{"url":"https://www.openwall.com/lists/oss-security/2020/06/18/1","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20200928 [SECURITY] [DLA 2385-1] linux-4.19 security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html"}]}]}}
