# CVE-2026-69159: freerdp3: FreeRDP is a free implementation of the Remote Desktop Protocol CVE-2026-69159 is fixed in 12 products on 1 platform, first by DEBIAN-CVE-2026-69159, released August 19, 2026. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2026-69159 - Priority: High - CVSS: 8.8 (medium) - EPSS: n/a - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Aug 19, 2026 ## Description FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.29.0, planar_decompress_plane_rle and planar_decompress_plane_rle_only in libfreerdp/codec/planar.c verify that a control byte exists but do not verify that the source buffer contains the zero to fifteen raw bytes declared by that control byte. A malicious RDP server can send a truncated planar bitmap or surface update whose final control byte claims additional raw bytes, causing the decoder to read beyond pSrcData while processing a color plane. This can crash the client and may disclose adjacent memory. This issue is fixed in version 3.29.0. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | freerdp almalinux 10 | 2:3.10.3-12.el10_2.10 | [ALSA-2026:61378](https://patchblox.com/security/data/fix/linux/alsa-2026-61378.md) | Aug 31, 2026 | | Linux | freerdp amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp ol 10 | 2:3.10.3-12.el10_2.10 | [ELSA-2026-61378-0](https://patchblox.com/security/data/fix/linux/elsa-2026-61378-0.md) | Sep 1, 2026 | | Linux | freerdp rocky 10 | 2:3.10.3-12.el10_2.10 | [RLSA-2026:61378](https://patchblox.com/security/data/fix/linux/rlsa-2026-61378.md) | Sep 1, 2026 | | Linux | freerdp-debuginfo amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp-debugsource amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp-devel almalinux 10 | 2:3.10.3-12.el10_2.10 | [ALSA-2026:61378](https://patchblox.com/security/data/fix/linux/alsa-2026-61378.md) | Aug 31, 2026 | | Linux | freerdp-devel amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp-devel ol 10 | 2:3.10.3-12.el10_2.10 | [ELSA-2026-61378-0](https://patchblox.com/security/data/fix/linux/elsa-2026-61378-0.md) | Sep 1, 2026 | | Linux | freerdp-libs almalinux 10 | 2:3.10.3-12.el10_2.10 | [ALSA-2026:61378](https://patchblox.com/security/data/fix/linux/alsa-2026-61378.md) | Aug 31, 2026 | | Linux | freerdp-libs amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp-libs ol 10 | 2:3.10.3-12.el10_2.10 | [ELSA-2026-61378-0](https://patchblox.com/security/data/fix/linux/elsa-2026-61378-0.md) | Sep 1, 2026 | | Linux | freerdp-libs-debuginfo amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp-server almalinux 10 | 2:3.10.3-12.el10_2.10 | [ALSA-2026:61378](https://patchblox.com/security/data/fix/linux/alsa-2026-61378.md) | Aug 31, 2026 | | Linux | freerdp-server amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp-server ol 10 | 2:3.10.3-12.el10_2.10 | [ELSA-2026-61378-0](https://patchblox.com/security/data/fix/linux/elsa-2026-61378-0.md) | Sep 1, 2026 | | Linux | freerdp-server-debuginfo amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | freerdp3 Debian 14 | 3.29.0+dfsg-1 | [DEBIAN-CVE-2026-69159](https://patchblox.com/security/data/fix/linux/debian-cve-2026-69159.md) | Aug 19, 2026 | | Linux | libwinpr almalinux 10 | 2:3.10.3-12.el10_2.10 | [ALSA-2026:61378](https://patchblox.com/security/data/fix/linux/alsa-2026-61378.md) | Aug 31, 2026 | | Linux | libwinpr amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | libwinpr ol 10 | 2:3.10.3-12.el10_2.10 | [ELSA-2026-61378-0](https://patchblox.com/security/data/fix/linux/elsa-2026-61378-0.md) | Sep 1, 2026 | | Linux | libwinpr-debuginfo amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | libwinpr-devel almalinux 10 | 2:3.10.3-12.el10_2.10 | [ALSA-2026:61378](https://patchblox.com/security/data/fix/linux/alsa-2026-61378.md) | Aug 31, 2026 | | Linux | libwinpr-devel amzn 2023 | 2:3.31.0-1.amzn2023 | [ALAS2023-2026-2142](https://patchblox.com/security/data/fix/linux/alas2023-2026-2142.md) | Sep 14, 2026 | | Linux | libwinpr-devel ol 10 | 2:3.10.3-12.el10_2.10 | [ELSA-2026-61378-0](https://patchblox.com/security/data/fix/linux/elsa-2026-61378-0.md) | Sep 1, 2026 | --- Data as of 2026-11-08T06:59:42Z UTC.
