Description
A use-after-free vulnerability exists in Samsung Escargot 5.0.2 in the buffer-access paths for ReloadableString and CompressibleString. Internal raw character accessors and the public StringRef::stringBufferAccessData() API did not preserve the lifetime of the underlying buffer while it remained in use. As a result, idle unloading or garbage-collection compression could release the buffer and leave a stale pointer. Subsequent access may cause the process to crash or, under allocation-dependent conditions, expose limited contents of another heap allocation. The issue was addressed by adding buffer-lifetime reference tracking and removing unsafe raw character accessors.

Description This issue can cause a heap-use-after-free when an embedder unloads a ReloadableString buffer while a previously returned raw character pointer remains in use. Successful triggering may cause the Escargot-based process to crash, resulting in a denial of service.
