CVE-2026-98576

In the Linux kernel, the following vulnerability has been resolved:

nfc: llcp: fix slab-out-of-bounds reads when logging service names

nfc_llcp_wks_sap() and nfc_llcp_build_sdreq_tlv() pass non-null- terminated strings to pr_debug() using the %s format specifier. The buffers are allocated via kmemdup() or come from netlink attributes and are not guaranteed to be null-terminated, causing __dynamic_pr_debug() to read beyond the allocated region:

KASAN: slab-out-of-bounds Read in __dynamic_pr_debug

Fix both call sites by using %.*s with the explicit length to limit the output to the actual length of the string.
