The vulnerability of the `of_unittest_changeset()` function in the `drivers/of/unittest.c` module of the Linux operating system’s device and open-source driver tree allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the ofunittestchangeset function in the drivers/of/unittest.c module of the Linux device and open-source kernel tree driver framework is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-46288

CVE-2026-46288 (Linux kernel). The issue is a use-after-free in unittest changeset handling of device-tree nodes: a pointer (parent) shares the same struct device_node as nchangeset, and of_node_put(nchangeset) can drop the refcount to zero while code still uses parent to inspect properties, lead...

CVE-2026-46288 of: unittest: fix use-after-free in of_unittest_changeset()

In the Linux kernel, the following vulnerability has been resolved: of: unittest: fix use-after-free in ofunittestchangeset The variable 'parent' is assigned the value of 'nchangeset' earlier in the function, meaning both point to the same struct devicenode. The call to ofnodeputnchangeset can...

CVE-2026-46288: Use After Free

In the Linux kernel, the following vulnerability has been resolved: of: unittest: fix use-after-free in ofunittestchangeset The variable 'parent' is assigned the value of 'nchangeset' earlier in the function, meaning both point to the same struct devicenode. The call to ofnodeputnchangeset can...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the reuse of a memory block released by the ofunittestchangeset function, potentially leading to...
