Go to dashboardIn the Linux kernel's NFC LLCP code, three error paths in the service-discovery request handler skip freeing already-queued TLV nodes, leaking kernel memory. The sources describe a leak, not code execution or data exposure.

In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: fix sdreq TLV list leak on parse/alloc/send failure
nfc_genl_llc_sdreq() builds a list of TLV nodes while walking nested netlink attrs, but 3 error paths (nested-attr parse failure, TLV alloc ENOMEM, nfc_llcp_send_snl_sdreq() failure) all skip freeing what was already queued.
Route them through a new free_list label, mirroring the SDRES path in the same file which already does this. Harmless on the success path too -- send_snl_sdreq() drains the list as it moves nodes, so it's already empty by the time free_list runs.
