• Memory Byte Array Element Delete Clears Whole Word Bug
  advisoryas affected products2026-09-10

  delete applied to an element of a bytes or string (via bytes(s)) array located in memory writes 32 zero bytes starting at that element instead of clearing only the element, corrupting up to 31 following bytes; only affects the default evmasm pipeline (with or without optimizer), not the IR pipeline

• Misordered Named Parameters in require with Custom Errors Bug
  advisoryas affected products2026-09-10

  IR-based code generator (--via-ir / viaIR: true); evmasm pipeline is unaffected. Fixed in 0.8.37.

• Spill Slot Collision Across Mutual Recursion Bug
  advisoryas tools2026-09-10It is written here as Solidity compiler (solc).

  Smart contract compiler; contains the IR pipeline's stack-to-memory mover ('stack limit evader') affected by the bug

• Unsound Spill In Mutual Recursion Bug
  advisoryas affected products2026-07-09It is written here as Solidity compiler (via-ir pipeline).

  Only the IR pipeline (--via-ir) is affected; the legacy evmasm pipeline is not affected. On 0.7.2-0.8.20 the bug additionally requires --optimize to be passed; on 0.8.21 and later it is independent of the optimizer setting. The IR pipeline was experimental until 0.8.13 (required --experimental-via-i

• Solidity 0.8.36 Release Announcement

  Compiler for the Solidity smart contract language

• Inheritance Order Reversal On Storage End Warning Bug
  advisoryas affected products2026-07-09

  Analysis-phase bug reversing the C3-linearized list of base contracts (linearizedBaseContracts annotation) when emitting Warning 3495 about custom storage layout placed too close to the end of storage; affects both IR and evmasm pipelines; pure Yul unaffected; transient storage unaffected. Fixed in
