CVE-2026-98579

About vulnerability

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.
