Linux Kernel Habanalabs Driver Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's Habanalabs driver. This issue arises in the 'user_mappings' information when a new context is opened right after the 'user_mapping' is captured, following a hard reset. The vulnerability affects the Linux kernel stable tree.

Impact

Exploitation of this vulnerability leads to a memory leak, which can cause increased memory usage and potentially allow for memory-related attacks.

Reproduction

The vulnerability can be reproduced by opening a new context in the Habanalabs driver immediately after capturing the user mapping and performing a hard reset. This sequence of actions causes the user mapping information to be cleared without properly releasing the memory, leading to a memory leak.

Remediation

Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
