CVE-2026-111381
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v2 that allows local attackers to corrupt heap memory via integer wraparound in bitmap size calculation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v2 that allows local attackers to corrupt heap memory via integer wraparound in bitmap size calculation. Attackers can craft a persistent cache v2 file with oversized width and height values that causes mismatched entry size accounting and fixed 16 KiB reads, leading to crashes or code execution when loaded.
