Severity CVSS v4.0:
Pending analysis
Type:
CWE-415 Double Free

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: misc: ljca: Fix double free in error handling path<br /> <br /> When auxiliary_device_add() returns error and then calls<br /> auxiliary_device_uninit(), callback function ljca_auxdev_release<br /> calls kfree(auxdev-&gt;dev.platform_data) to free the parameter data<br /> of the function ljca_new_client_device. The callers of<br /> ljca_new_client_device shouldn&amp;#39;t call kfree() again<br /> in the error handling path to free the platform data.<br /> <br /> Fix this by cleaning up the redundant kfree() in all callers and<br /> adding kfree() the passed in platform_data on errors which happen<br /> before auxiliary_device_init() succeeds .
