DEBIAN-CVE-2026-45868
No affected components available
In the Linux kernel, the following vulnerability has been resolved: pinctrl: single: fix refcount leak in pcs_add_gpio_func() of_parse_phandle_with_args() returns a device_node pointer with refcount incremented in gpiospec.np. The loop iterates through all phandles but never releases the reference, causing a refcount leak on each iteration. Add of_node_put() calls to release the reference after extracting the needed arguments and on the error path when devm_kzalloc() fails. This bug was detected by our static analysis tool and verified by my code review.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges.
