Last modified Jun 17, 2026

CVE-2018-10540 is a vulnerability of currently unknown severity. An issue was discovered in WavPack 5.1.0 and earlier for W64 input. Out-of-bounds writes can occur because ParseWave64HeaderConfig in wave64.c does not validate the sizes of unknown chunks before attempting memory allocation, related to a lack of integer-overflow protection within a bytes_to_copy calculation and subsequent malloc call, leading to insufficient memory allocation.. EPSS estimates a 1.67% chance of exploitation in the next 30 days.
