Vulnerability from github – Published: 2021-08-25 20:51 – Updated: 2023-06-13 18:08

Summary

Data races in hashconsing

Details

Affected versions of hashconsing implements Send/Sync for its HConsed type without restricting it to Sendable types and Syncable types. This allows non-Sync types such as Cell to be shared across threads leading to undefined behavior and memory corruption in concurrent programs.

Severity ?

7.5 (High)
