Overview

CVE-2026-43196 is a high-severity vulnerability. It was published on May 6, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, 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:

soc: ti: pruss: Fix double free in pruss_clk_mux_setup()

In the pruss_clk_mux_setup(), the devm_add_action_or_reset() indirectly

calls pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np)

on the error path. However, after the devm_add_action_or_reset()

returns, the of_node_put(clk_mux_np) is called again, causing a double

free.

Fix by returning directly, to avoid the duplicate of_node_put().

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.
