      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: Fix use-after-free in cifs_try_adding_channels()\n\ncifs_try_adding_channels() takes a temporary reference to an interface\nbefore dropping iface_lock. If cifs_ses_add_channel() fails, it drops\nthat reference and then increments iface->weight_fulfilled.\n\nA concurrent interface list refresh can remove the list reference while\nchannel creation is in progress. In that case, the failure-path\nkref_put() releases the last reference and frees iface. Updating\nweight_fulfilled afterward then accesses freed memory.\n\nIncrement weight_fulfilled before dropping the temporary reference,\nkeeping iface alive for the final access.",
