GHSA-X858-GX5H-MFP9

Vulnerability from github – Published: 2024-05-21 15:31 – Updated: 2025-09-23 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

i2c: acpi: fix resource leak in reconfiguration device addition

acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a reference on the adapter which is never released which will result in a reference count leak and render the adapter unremovable. Make sure to put the adapter after creating the client in the same manner that we do for OF.
