Vulnerability from github – Published: 2021-08-25 20:43 – Updated: 2023-06-13 21:37

Summary

Memory corruption in smallvec

Details

Attempting to call grow on a spilled SmallVec with a value less than the current capacity causes corruption of memory allocator data structures. An attacker that controls the value passed to grow may exploit this flaw to obtain memory contents or gain remote code execution.

Severity ?

9.8 (Critical)
