Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The issue is related to the i40e component of the Linux kernel, where a variable `vf` may be used uninitialized, potentially causing servers to hang in rare conditions with reset races. The root cause is the use of two sources for information, leading to interchangeable use of variables `v` and `vf`, which could result in a stale `vf` pointing to a different or unintended `vf`. The fix involves removing the redundant `v` variable and iterating via a single `VF` pointer to guarantee its validity. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a null pointer dereference in the i40e component of the Linux kernel. This occurs when synchronizing VSI filters, potentially allowing an attacker to cause a denial of service. A new flag, I40E VSI RELEASING, has been added to signal the deletion and release of VSI resources, synchronizing the thread with the sync filters subtask. Without this patch, it is possible to start updating the VSI filter list after the VSI is removed, causing a kernel oops. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
