GHSA-PHFR-35GX-VF86
Vulnerability from github – Published: 2026-02-14 18:30 – Updated: 2026-03-18 15:30In the Linux kernel, the following vulnerability has been resolved:
drm/xe/nvm: Fix double-free on aux add failure
After a successful auxiliary_device_init(), aux_dev->dev.release (xe_nvm_release_dev()) is responsible for the kfree(nvm). When there is failure with auxiliary_device_add(), driver will call auxiliary_device_uninit(), which call put_device(). So that the .release callback will be triggered to free the memory associated with the auxiliary_device.
Move the kfree(nvm) into the auxiliary_device_init() failure path and remove the err goto path to fix below error.

Mitigation
Choose a language that provides automatic memory management.
Mitigation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Use a static analysis tool to find double free instances.
No CAPEC attack patterns related to this CWE.
