CVE-2026-23137

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> of: unittest: Fix memory leak in unittest_data_add()<br /> <br /> In unittest_data_add(), if of_resolve_phandles() fails, the allocated<br /> unittest_data is not freed, leading to a memory leak.<br /> <br /> Fix this by using scope-based cleanup helper __free(kfree) for automatic<br /> resource cleanup. This ensures unittest_data is automatically freed when<br /> it goes out of scope in error paths.<br /> <br /> For the success path, use retain_and_null_ptr() to transfer ownership<br /> of the memory to the device tree and prevent double freeing.
