GHSA-6HFV-88F5-HJF6

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-17 21:31

Details

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

PCI: dwc: Deallocate EPC memory on dw_pcie_ep_init() errors

If dw_pcie_ep_init() fails to perform any action after the EPC memory is initialized and the MSI memory region is allocated, the latter parts won't be undone thus causing a memory leak. Add a cleanup-on-error path to fix these leaks.
