CVE-2026-43196 Details
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().
A double free vulnerability has been identified in the Linux kernel's PRUSS (Programmable Real-time Unit Subsystem) driver. This issue arises in the 'pruss_clk_mux_setup()' function, where the 'devm_add_action_or_reset()' call indirectly triggers 'pruss_of_free_clk_provider()'. The latter function, on its error path, calls 'of_node_put(clk_mux_np)', which is then erroneously called again after 'devm_add_action_or_reset()' returns, leading to a double free condition. The vulnerability affects several versions of the Linux kernel.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version.
