Description
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.
