{"id":"ALPINE-CVE-2022-26495","details":"In nbd-server in nbd before 3.24, there is an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name, resulting in a write to a dangling pointer. This issue exists for the NBD_OPT_INFO, NBD_OPT_GO, and NBD_OPT_EXPORT_NAME messages.","modified":"2026-11-03T07:31:22.814771063Z","published":"2022-03-06T06:15:07.303Z","upstream":["CVE-2022-26495"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-26495"}],"affected":[{"package":{"name":"nbd","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}},{"package":{"name":"nbd","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/nbd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.24-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-26495.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
