Description OSIDB Bzimport 2025-06-18 12:07:14 UTC 
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.
