Description OSIDB Bzimport 2025-12-30 13:03:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

xhci: dbc: Fix memory leak in xhci_alloc_dbc()

If DbC is already in use, then the allocated memory for the xhci_dbc struct
doesn't get freed before returning NULL, which leads to a memleak.
