{"id":"CVE-2026-92627","published":"2026-09-16T16:17:23.993","lastModified":"2026-09-18T19:34:36.657","description":"A heap-use-after-free vulnerability exists in H5T__conv_f_f() in src/H5Tconv.c in HDF5 before 1.14.2. When converting a compound datatype containing floating-point members during a dataset read, a temporary buffer allocated with calloc() is freed and subsequently read from within the same conversion routine. An attacker who can supply a crafted HDF5 file containing a specially constructed compound datatype can trigger the use-after-free when the file is parsed by an application that reads the affected dataset, such as h5dump. This can result in a crash and, depending on heap layout and allocator behavior, may be exploitable for further memory corruption up to remote code execution.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-416"],"vendors":[],"products":[],"references":[{"url":"https://pulsesecurity.co.nz/advisories/hdf5-memory-corruption","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
