      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: fix use-after-free in nfc_get_local_general_bytes\n\nCommit 6709d4b7bc2e (\"net: nfc: Fix use-after-free caused by\nnfc_llcp_find_local\") attempted to fix a use-after-free (UAF) issue by\ninvoking nfc_llcp_local_put(local) after accessing local->gb. However,\nif the reference count drops to zero, local is freed immediately,\nleading to a use-after-free when callers access the returned pointer.\nAlternative approaches using dynamic allocation (e.g. kmemdup) introduced\nmemory leaks because callers consistently treat the returned pointer as\nborrowed memory.\n\nFix this properly by refactoring nfc_llcp_general_bytes() and\nnfc_get_local_general_bytes() to accept a caller-provided output buffer\n(out_gb) and its maximum length (gb_max_len). The general bytes are\nsafely copied into out_gb before calling nfc_llcp_local_put(local),\nensuring safe lifetime management without ownership transfer complications.\n\nUpdate all callers across drivers (microread, pn533, pn544, st21nfca,\ndigital_dep, and nci) to provide their own destination buffers and pass\nthem to nfc_get_local_general_bytes().",
