简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- nfcllcp修复 nfc_llcp_send_ui_frame() 中的内存泄漏。 syzbot 报告了与 NFC、struct nfc_llcp_sock、sk_buff、nfc_dev 等相关的多个内存泄漏。[0] 主要日志暗示 nfc_llcp_send_ui_frame() 无法分配 skb这是因为 sock_error(sk) 为 -ENXIO 所致。当 local_cleanup() 破坏 struct nfc_llcp_local 时nfc_llcp_socket_release() 设置 ENXIO。问题在于 nfc_llcp_send_ui_frame() 和 local_cleanup() 之间无同步而在 local_cleanup() 中清除 skb 之后可能将其放入 local->tx_queueCPU1 CPU2 ---- ---- nfc_llcp_send_ui_frame() local_cleanup () |- do { ' |- pdu = nfc_alloc_send_skb(..., &err) | 。 | |- nfc_llcp_socket_release(local, false, ENXIO); | |- skb_queue_purge(&local->tx_queue); | | | |- skb_queue_tail(&local->tx_queue, pdu); | ... |- pdu = nfc_alloc_send_skb(..., &err) | ^.______。”只有在 nfc_llcp_remove_local() 取消与 llcp_devices 的链接之后才会为结构 nfc_llcp_local 调用 local_cleanup()。如果随后保持 local->tx_queue.lock则可同步线程和 nfc_llcp_send_ui_frame()。让我们执行此操作并在 nfc_llcp_send_ui_frame() 中将 skb 排入 local->tx_queue 之前检查 list_empty(&local->list)。 [0][56.074943[ T6096] llcpnfc_llcp_send_ui_frame无法分配 PDU (error=-6) [ 64.318868][ T5813] kmemleak6 个新的可疑内存泄漏请参阅 /sys/kernel/debug/kmemleakBUG内存泄漏未引用对象 0xffff8881272f6800 (大小 1024): comm syz.0.17, pid 6096, jiffies 4294942766 十六进制转储 (前 32 字节): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ....... 27 00 03 40 00 00 00 00 00 00 00 00 00 00 00 00 '..@....... 回溯 (crc da58d84d)kmemleak_alloc_recursive include/ linux/kmemleak.h:44 [内联] slab_post_alloc_hook mm/slub.c:4979 [内联] slab_alloc_node mm/slub.c:5284 [内联] __do_kmalloc_node mm/slub.c:5645 [内联] __kmalloc_noprof+0x3e3/0x6b0 mm/ slub.c:5658 kmalloc_noprof include/linux/slab.h:961 [inline] sk_prot_alloc+0x11a/0x1b0 net/core/sock.c:2239 sk_alloc+0x36/0x360 net/core/sock.c:2295 nfc_llcp_sock_alloc+0x37/ 0x130 net/nfc/llcp_sock.c:979 llcp_sock_create+0x71/0xd0 net/nfc/llcp_sock.c:1044 nfc_sock_create+0xc9/0xf0 net/nfc/af_nfc.c:31 __sock_create+0x1a9/0 x340 net/socket.c:1605 sock_create net/socket.c:1663 [内联]
