When it parses a specially crafted .pof file, the parser accesses memory beyond the bounds of an allocated buffer. The vulnerability does not require any FPGA hardware to trigger and can simply be exercised by running the utility against a maliciously crafted file. The out\u2011of\u2011bounds read may expose sensitive data that resides on the heap, potentially leading to information disclosure or, if the heap is overwritten, a crash or other downstream failures.", "risk_and_exploitability": "The CVSS base score of 7.1 indicates a high\u2011risk flaw. No exploit probability was reported and the vulnerability is not listed in CISA\u2019s KEV catalog. Because the attack only requires a crafted .pof file and can be exercised locally by anyone who can run openFPGALoader, the attack vector is inferred to be local or remote code running on the same system. An attacker could obtain confidential data from the process\u2019s memory or cause denial of service by crashing the program."}}}}, "created": "2026-04-07T06:54:36.475933+00:00", "updated": "2026-04-07T09:37:40.082907+00:00", "vendors": ["trabucayre", "trabucayre$PRODUCT$openfpgaloader"]}
