CVE-2026-16280 GPU DDK - Integer overflow in _PMRLogicalOffsetToPhysicalOffset

An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in...

CVE-2026-16280

CVE-2026-16280 affects GPU DDK, specifically the PMRLogicalOffsetToPhysicalOffset function. An integer overflow for PMRs larger than 4 GB causes 32-bit truncation of address computations, leading to incorrect GPU MMU mappings. This can enable a non-privileged user to access unintended physical me...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the macedecodeframe process. An attacker can corrupt heap memory and potentially execute arbitrary code by supplying a crafted CAF file with malicious bytesperpacket and framesperpacket values that...

frp: Unauthenticated Remote Denial of Service in the frp SSH Tunnel Gateway via Integer Overflow

Summary An integer-overflow vulnerability in the frp server's optional SSH Tunnel Gateway lets any unauthenticated remote attacker crash the entire frps process with a single five-byte message. When the gateway parses an SSH exec channel request in pkg/ssh/server.go, it adds a small constant to a...
