{"id":"AZL-107129","summary":"CVE-2026-106435 affecting package python-pymongo 4.2.0-9","details":"The MongoDB Python Driver's binary accelerator can read outside a buffer when an application decodes malformed BSON containing a truncated regular-expression element without a trailing NUL byte. An actor who can supply BSON to the documented decode or decode_all API can cause the application process to terminate when the C extension is loaded. The driver's normal database wire-protocol path does not reach this code.","modified":"2026-10-12T05:33:09Z","published":"2026-10-08T21:17:51Z","upstream":["CVE-2026-106435"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106435"}],"affected":[{"package":{"name":"python-pymongo","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-pymongo"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.2.0-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-107129.json"}}],"schema_version":"1.9.0"}
