CVE-2024-45056 is a medium-severity vulnerability affecting zksolc, the Solidity compiler for ZKsync, specifically versions prior to 1.5.3. It stems from an incorrect sign extension in the LLVM backend when optimizing a specific bitwise operation, leading to incorrect code generation for EraVM targets. The vulnerability has a CVSS score of 5.9 (MEDIUM) due to its high impact on integrity (I:H) and high attack complexity (AC:H), though it requires no user interaction (UI:N) and is network-exploitable (AV:N). Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed on the CISA KEV catalog.
