In the Linux kernel, the following vulnerability has been resolved:
tipc: check attribute length for bearer name
syzbot reported uninit-value: ===================================================== BUG: KMSAN: uninit-value in string_nocheck lib/vsprintf.c:644 [inline] BUG: KMSAN: uninit-value in string+0x4f9/0x6f0 lib/vsprintf.c:725 string_nocheck lib/vsprintf.c:644 [inline] string+0x4f9/0x6f0 lib/vsprintf.c:725 vsnprintf+0x2222/0x3650 lib/vsprintf.c:2806 vprintk_store+0x537/0x2150 kernel/printk/printk.c:2158 vprintk_emit+0x28b/0xab0 kernel/printk/printk.c:2256 vprintk_default+0x86/0xa0 kernel/printk/printk.c:2283 vprintk+0x15f/0x180 kernel/printk/printk_safe.c:50 _printk+0x18d/0x1cf kernel/printk/printk.c:2293 tipc_enable_bearer net/tipc/bearer.c:371 [inline] __tipc_nl_bearer_enable+0x2022/0x22a0 net/tipc/bearer.c:1033 tipc_nl_bearer_enable+0x6c/0xb0 net/tipc/bearer.c:1042 genl_family_rcv_msg_doit net/netlink/genetlink.c:731 [inline]
- Do sanity check the attribute length for TIPC_NLA_BEARER_NAME. - Do not use 'illegal name' in printing message.
