CVE-2026-98577

The Linux kernel contains a vulnerability in the nfc_llcp_wks_sap() function, which allows for WKS SAP hijacking . The root cause is that the function compares only service_name_len bytes, leading to a prefix match where a short service name (e.g., "u") incorrectly matches longer WKS strings (e.g...

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: fix slab-out-of-bounds reads when logging service names nfcllcpwkssap and nfcllcpbuildsdreqtlv pass non-null- terminated strings to prdebug using the %s format specifier. The buffers are allocated via kmemdup or come...

CVE-2026-98576

The Linux kernel contains a vulnerability in the nfc: llcp component where the functions nfc_llcp_wks_sap() and nfc_llcp_build_sdreq_tlv() pass non-null-terminated strings to pr_debug() using the %s format specifier. Because these buffers are allocated via kmemdup() or sourced from netlink attrib...
