kernel: Use After Free in unix_gc() which could result in a local privilege escalation

A vulnerability was found in unixdgramrecvmsg in net/unix/afunix.c in the Linux kernel's garbage collection for Unix domain socket file handlers. In this flaw, a missing cleanup may lead to a use-after-free due to a race problem. This flaw allows a local user to crash the system or escalate their...

Duplicate NFTs Can Be Minted if payableToken Has a Callback Attached to it

Lines of code Vulnerability details Impact The mintToken function is called to mint unique tokens from an ERC721 collection. This function will either require users to provide a merkle proof to claim an airdropped token or pay a fee in the form of a payableToken. However, because the payableToken...

Gas costs will likely result in any fees sent to the Splitter being economically unviable to recover.

Lines of code Vulnerability details Impact Collection owners will likely lose money by claiming fees unless the fees from a single NFT sale outweighs the cost of claiming it not guaranteed. Proof of Concept Consider a new Collection with a RoyaltyVault and Splitter set and a nonzero mint fee. Whe...
