CVE-2026-121954
FreeRDP before 3.32.2 Heap Out-of-Bounds Write in Planar Codec
CVSS Score
6.5
EPSS Score
0.0%
EPSS Percentile
0th
FreeRDP before 3.32.2 has a heap out-of-bounds write in the planar codec because freerdp_bitmap_planar_context_reset commits new dimensions before buffer reallocation succeeds, and a failed ResetGraphics is only logged. A malicious RDP server can send an oversized ResetGraphics PDU, then a GFX PLANAR command, to corrupt client heap memory and crash the client.
