{"id":"CVE-2026-109947","summary":"FreeRDP 3.20.1 before 3.32.0 Unbounded Allocation via drive_process_irp_read","details":"FreeRDP from 3.20.1 before 3.32.0 contains an uncontrolled resource allocation vulnerability that allows malicious RDP servers to exhaust client memory via oversized drive redirection read requests. Attackers can send IRP_MJ_READ with Length 0xffffffff, causing roughly 4 GiB of zeroed allocation on 64-bit builds or an under-reserved buffer on 32-bit builds.","aliases":["GHSA-q56j-jjh6-38jf"],"modified":"2026-10-15T02:47:22.950894884Z","published":"2026-10-13T13:27:14.425Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109947.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-770"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109947.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-q56j-jjh6-38jf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109947"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/freerdp-3.20.1-before-3.32.0-unbounded-allocation-via-drive-process-irp-read"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"7418bc7b7c880a87edade60282f6aeeacd640e47"},{"fixed":"d27a4f7c1c63b62a5e60e5d939ad116cfb58ffc1"}],"database_specific":{"extracted_events":[{"introduced":"3.20.1"},{"fixed":"3.32.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109947.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
