CVE-2026-81886

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Windows 64-bit crash-dump dmp64 parser was vulnerable because the Windows dmp64 parser used an input-controlled physical-memory-run PageCount directly as the bound of a per-page allocation loo...

CVE-2026-81886

radare2 is a UNIX-like reverse engineering framework. Prior to 6.2.0 , its Windows 64-bit crash-dump (dmp64) parser used an input-controlled physical-memory-run PageCount directly as the bound of a per-page allocation loop without validating the count against the actual dump size. Opening a small...
