CVE-2021-26347: Improper Validation of Specified Quantity in Input

Failure to validate the integer operand in ASP AMD Secure Processor bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service...

Input validation

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "virtext" field, this issue could allow a malicious...

Griefing attack on migrateLPT can prevent token transfer to L2

Handle harleythedog Vulnerability details Impact In L1Migrator.sol the function migrateLPT can be called by anyone. A malicious user can call migrateLPT with a small maxSubmissionCost argument to intentionally make the retryable ticket creation fail. This will lock the LPT in the L1 escrow. Now,...

Admin can rug L2 Escrow tokens leading to reputation risk

Handle harleythedog Vulnerability details Impact The L1Escrow contract has the function approve that is callable by the admin to approve an arbitrary spender with an arbitrary amount so they can steal all of the escrow's holdings if they want. Even if the admin is well intended, the contract can...

L1Migrator.migrateLPT` can be used to take away protocol's access to LPT tokens in BridgeMinter

Handle Ruhum Vulnerability details Vulnerability details Impact Same thing as the ETH issue I reported earlier. I wasn't sure if those are supposed to be a single issue or not. The concept is the same. But, now you lose LPT tokens. The L1Migrator.migrateLPT function can be called by anyone. It...
