Overview

CVE-2026-93796 is a high-severity vulnerability. It was published on September 24, 2026 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

wifi: iwlwifi: pcie: null RX pointers after free

When iwl_pcie_tx_init() fails after RX init, nic init unwinds via

iwl_pcie_rx_free().

The freed RX members stayed non-NULL on the live transport object,

so later teardown or retry could touch stale RX state.

Set rx_pool, global_table, rxq, and alloc_page to NULL after free

to make repeated cleanup and retry paths safe.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
