CVE-2024-11991 (GCVE-0-2024-11991)
Vulnerability from cvelistv5 – Published: 2024-12-09 14:38 – Updated: 2024-12-09 15:07
VLAI?
Summary
Motoko's incremental garbage collector is impacted by an uninitialized memory access bug, caused by incorrect use of write barriers in a few locations. This vulnerability could potentially allow unauthorized read or write access to a Canister's memory. However, exploiting this bug requires the Canister to enable the incremental garbage collector or enhanced orthogonal persistence, which are non-default features in Motoko.
Severity ?
