Vulnerability from github – Published: 2025-03-14 00:30 – Updated: 2025-03-14 00:30

Details

In the Linux kernel, the following vulnerability has been resolved:

habanalabs: fix possible memory leak in MMU DR fini

This patch fixes what seems to be copy paste error.

We will have a memory leak if the host-resident shadow is NULL (which will likely happen as the DR and HR are not dependent).

Severity ?

5.5 (Medium)
