following vulnerability has been resolved:\n\nnfc: llcp: fix slab-out-of-bounds reads when logging service names\n\nnfc_llcp_wks_sap() and nfc_llcp_build_sdreq_tlv() pass non-null-\nterminated strings to pr_debug() using the %s format specifier.\nThe buffers are allocated via kmemdup() or come from netlink\nattributes and are not guaranteed to be null-terminated, causing\n__dynamic_pr_debug() to read beyond the allocated region:\n\n  KASAN: slab-out-of-bounds Read in __dynamic_pr_debug\n\nFix both call sites by using %.*s with the explicit length to limit\nthe output to the actual length of the string.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
