FreeRDP from 3.0.0-beta1 before 3.32.0 contains a use-after-free vulnerability in smartcard handling that allows attackers to access a freed smartcard handle object after an invalid connect operation. Attackers can trigger an invalid smartcard connect operation to cause reuse of the freed handle, leading to memory corruption or crashes.

The Rocky Linux 10.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2026_94514 advisory.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:1205 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-111880:
    FreeRDP versions from 2.0.0 before 3.32.0 contain a heap out-of-bounds write in the server hash-callback     NTLM path that fails to validate the MIC offset. Unauthenticated attackers can send a crafted     AUTHENTICATE_MESSAGE with a backward session-key offset and MIC offset to write 16 zero bytes beyond the     allocation.

    CVE-2026-111379:
    FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v3 that     allows local attackers to corrupt memory by supplying a crafted v3 persistent cache file. Attackers can     set large width and height values that wrap the size calculation in persist_cache_get_data, causing fread     to overflow an undersized buffer and potentially execute code.

    CVE-2026-110839:
    FreeRDP 3.3.0 before 3.32.0, when built with WINPR_UTILS_IMAGE_JPEG=ON, has a heap-based out-of-bounds     write in winpr_convert_from_jpeg because grayscale JPEG buffers are sized from one input component rather     than three BGR output components. A malicious RDP server can offer a grayscale JPEG via clipboard     redirection, corrupting client memory and crashing it when the item is pasted as CF_DIB bitmap data.

    CVE-2026-110837:
    FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer     overflow in freerdp_dsp_decode_mp3 because the right-channel PCM pointer is offset by a byte count treated     as short elements. A malicious RDP server can send MP3 audio over rdpsnd so decoded samples cross the heap     allocation, crashing the client.

    CVE-2026-109676:
    FreeRDP from 3.0.0-beta1 before 3.32.0 contains a use-after-free vulnerability in smartcard handling that     allows attackers to access a freed smartcard handle object after an invalid connect operation. Attackers     can trigger an invalid smartcard connect operation to cause reuse of the freed handle, leading to memory     corruption or crashes.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - FreeRDP from 3.0.0-beta1 before 3.32.0 contains a use-after-free vulnerability in smartcard handling that     allows attackers to access a freed smartcard handle object after an invalid connect operation. Attackers     can trigger an invalid smartcard connect operation to cause reuse of the freed handle, leading to memory     corruption or crashes. (CVE-2026-109676)

Note that Nessus relies on the presence of the package as reported by the vendor.
