{"id":"JLSEC-2026-765","summary":"Remote packet capture support is disabled by default in libpcap","details":"Remote packet capture support is disabled by default in libpcap.  When a user builds libpcap with remote packet capture support enabled, one of the functions that become available is `pcap_findalldevs_ex()`.  One of the function arguments can be a filesystem path, which normally means a directory with input data files.  When the specified path cannot be used as a directory, the function receives NULL from opendir(), but does not check the return value and passes the NULL value to readdir(), which causes a NULL pointer derefence.","modified":"2026-07-25T18:24:52.933347106Z","published":"2026-07-15T15:14:16.023Z","upstream":["CVE-2024-8006","GHSA-gj9v-677h-mwcx","EUVD-2024-48881"],"database_specific":{"license":"CC-BY-4.0","sources":[{"database_specific":{"status":"Analyzed"},"id":"CVE-2024-8006","imported":"2026-07-17T22:38:20.538Z","modified":"2026-06-17T08:21:39.470Z","published":"2024-08-31T00:15:05.743Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2024-8006","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2024-8006"},{"published":"2024-08-31T00:31:05Z","url":"https://api.github.com/advisories/GHSA-gj9v-677h-mwcx","html_url":"https://github.com/advisories/GHSA-gj9v-677h-mwcx","id":"GHSA-gj9v-677h-mwcx","imported":"2026-07-17T22:38:20.684Z","modified":"2024-08-31T00:31:11Z"},{"published":"2024-08-30T23:53:11Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2024-48881","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2024-48881","id":"EUVD-2024-48881","imported":"2026-07-17T22:38:25.361Z","modified":"2024-09-03T19:17:49Z"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-gj9v-677h-mwcx"},{"type":"WEB","url":"https://github.com/the-tcpdump-group/libpcap/commit/0f8a103469ce87d2b8d68c5130a46ddb7fb5eb29"},{"type":"WEB","url":"https://github.com/the-tcpdump-group/libpcap/commit/8a633ee5b9ecd9d38a587ac9b204e2380713b0d6"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-8006"}],"affected":[{"package":{"name":"libpcap_jll","ecosystem":"Julia","purl":"pkg:julia/libpcap_jll?uuid=f78539f5-9ba6-5ded-ae79-6d41194c59b7"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.10.5+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-765.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"}]}
