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.

How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
