Linux Kernel Futex Error Handling Vulnerability in Process Copying

A vulnerability has been identified in the Linux kernel's handling of futex hash allocation during the process copying operation. The issue arises because the error exit path from the futex hash allocation function is incorrect. When an error occurs, the process fails to properly acquire necessary locks, leading to potential inconsistencies. This vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability could lead to improper management of process locks, potentially causing synchronization issues or inconsistencies in process handling.

Remediation

Users can upgrade to the latest version of the Linux kernel stable tree to address this vulnerability.
