AI-suggested

A patch is available and should be applied to affected Linux kernel versions to resolve the memory leaks and crashes. The fix corrects the queue allocation and vport pointer handling during soft resets, preventing use-after-free conditions and limbo states. Users should update to the fixed kernel versions listed in the advisory. No additional mitigation steps are required beyond applying the official kernel updates and rebooting the system to activate the fixes.

Description

CVE-2024-44964 is a high-severity vulnerability in the Linux kernel's idpf driver that causes memory leaks and crashes during a soft reset. The issue stems from a use-after-free condition caused by improper handling of vport pointers and queue allocations during reset operations. This flaw leads to fragile logic that can double memory consumption and leave the device in an inconsistent state, including partially allocated vports and memory leaks when interfaces are toggled. The vulnerability affects multiple Linux kernel versions prior to fixed releases. A patch is available that corrects the queue allocation logic and restores proper state management to prevent crashes and leaks.
