High CVSS 7.5

E6878-370 with versions of 10.0.3.1(H557SP27C233), 10.0.3.1(H563SP1C00), 10.0.3.1(H563SP1C233) has a use after free vulnerability. The software references memory after it has been freed in certain scenario, the attacker does a series of crafted operations through web portal, successful exploit could cause a use after free condition which may lead to malicious code execution.

Matched remediation archetype

Use-after-free, double free, and expired resource use

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace ownership, references, callbacks, asynchronous tasks, and teardown paths around the affected object or resource.
  • Identify reachable inputs and timing or state transitions that can release the object while references remain.
  • Confirm affected builds, allocators, feature flags, architectures, and process privileges.

Remediate safely

  • Apply the maintained ownership or lifetime fix and rebuild all artifacts containing the affected native code.
  • Use explicit ownership, safe reference management, cancellation and join semantics, and idempotent teardown.
  • Add deterministic lifetime tests plus isolated sanitizer and concurrency coverage for shutdown and error paths.
