| Title | https://github.com/HDFGroup/hdf5 HDF5 1.14.6 NULL Pointer Dereference |
|---|
| Description | A null pointer read vulnerability was discovered in the H5O__cache_chk_serialize function within the HDF5 Library. This issue occurs when processing certain files, leading to a potential application crash.
The vulnerability arises in the H5O__cache_chk_serialize function defined in src/H5Ocache.c at line 788.
The reason is that the function H5O__cache_chk_serialize did not check the validity of chk_proxy->oh->chunk[chk_proxy->chunkno].image before calling H5MM_memcpy, resulting in a null pointer dereference read. |
