Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9820 vulnerabilities reference this CWE, most recent first.

Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: wilc1000: prevent use-after-free on vif when cleaning up all interfaces

wilc_netdev_cleanup currently triggers a KASAN warning, which can be observed on interface registration error path, or simply by removing the module/unbinding device from driver:

echo spi0.1 > /sys/bus/spi/drivers/wilc1000_spi/unbind

David Mosberger-Tan initial investigation [1] showed that this use-after-free is due to netdevice unregistration during vif list traversal. When unregistering a net device, since the needs_free_netdev has been set to true during registration, the netdevice object is also freed, and as a consequence, the corresponding vif object too, since it is attached to it as private netdevice data. The next occurrence of the loop then tries to access freed vif pointer to the list to move forward in the list.

Fix this use-after-free thanks to two mechanisms: - navigate in the list with list_for_each_entry_safe, which allows to safely modify the list as we go through each element. For each element, remove it from the list with list_del_rcu - make sure to wait for RCU grace period end after each vif removal to make sure it is safe to free the corresponding vif too (through unregister_netdev)

Since we are in a RCU "modifier" path (not a "reader" path), and because such path is expected not to be concurrent to any other modifier (we are using the vif_mutex lock), we do not need to use RCU list API, that's why we can benefit from list_for_each_entry_safe.

Vulnerability from github – Published: 2025-07-09 12:31 – Updated: 2026-06-19 15:33
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_core: Fix use-after-free in vhci_flush()

syzbot reported use-after-free in vhci_flush() without repro. [0]

From the splat, a thread close()d a vhci file descriptor while its device was being used by iotcl() on another thread.

Once the last fd refcnt is released, vhci_release() calls hci_unregister_dev(), hci_free_dev(), and kfree() for struct vhci_data, which is set to hci_dev->dev->driver_data.

The problem is that there is no synchronisation after unlinking hdev from hci_dev_list in hci_unregister_dev(). There might be another thread still accessing the hdev which was fetched before the unlink operation.

We can use SRCU for such synchronisation.

Let's run hci_dev_reset() under SRCU and wait for its completion in hci_unregister_dev().

Another option would be to restore hci_dev->destruct(), which was removed in commit 587ae086f6e4 ("Bluetooth: Remove unused hci-destruct cb"). However, this would not be a good solution, as we should not run hci_unregister_dev() while there are in-flight ioctl() requests, which could lead to another data-race KCSAN splat.

Note that other drivers seem to have the same problem, for exmaple, virtbt_remove().

[0]\n\nFrom the splat, a thread close()d a vhci file descriptor while\nits device was being used by iotcl() on another thread.\n\nOnce the last fd refcnt is released, vhci_release() calls\nhci_unregister_dev(), hci_free_dev(), and kfree() for struct\nvhci_data, which is set to hci_dev-\u003edev-\u003edriver_data.\n\nThe problem is that there is no synchronisation after unlinking\nhdev from hci_dev_list in hci_unregister_dev().  There might be\nanother thread still accessing the hdev which was fetched before\nthe unlink operation.\n\nWe can use SRCU for such synchronisation.\n\nLet\u0027s run hci_dev_reset() under SRCU and wait for its completion\nin hci_unregister_dev().\n\nAnother option would be to restore hci_dev-\u003edestruct(), which was\nremoved in commit 587ae086f6e4 (\"Bluetooth: Remove unused\nhci-destruct cb\").  However, this would not be a good solution, as\nwe should not run hci_unregister_dev() while there are in-flight\nioctl() requests, which could lead to another data-race KCSAN splat.\n\nNote that other drivers seem to have the same problem, for exmaple,\nvirtbt_remove().\n\n[0]:\nBUG: KASAN: slab-use-after-free in skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]\nBUG: KASAN: slab-use-after-free in skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937\nRead of size 8 at addr ffff88807cb8d858 by task syz.1.219/6718\n\nCPU: 1 UID: 0 PID: 6718 Comm: syz.1.219 Not tainted 6.16.0-rc1-syzkaller-00196-g08207f42d3ff #0 PREEMPT(full)\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025\nCall Trace:\n \u003cTASK\u003e\n dump_stack_lvl+0x189/0x250 lib/dump_stack.c:120\n print_address_description mm/kasan/report.c:408 [inline]\n print_report+0xd2/0x2b0 mm/kasan/report.c:521\n kasan_report+0x118/0x150 mm/kasan/report.c:634\n skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]\n skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937\n skb_queue_purge include/linux/skbuff.h:3368 [inline]\n vhci_flush+0x44/0x50 drivers/bluetooth/hci_vhci.c:69\n hci_dev_do_reset net/bluetooth/hci_core.c:552 [inline]\n hci_dev_reset+0x420/0x5c0 net/bluetooth/hci_core.c:592\n sock_do_ioctl+0xd9/0x300 net/socket.c:1190\n sock_ioctl+0x576/0x790 net/socket.c:1311\n vfs_ioctl fs/ioctl.c:51 [inline]\n __do_sys_ioctl fs/ioctl.c:907 [inline]\n __se_sys_ioctl+0xf9/0x170 fs/ioctl.c:893\n do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline]\n do_syscall_64+0xfa/0x3b0 arch/x86/entry/syscall_64.c:94\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\nRIP: 0033:0x7fcf5b98e929\nCode: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 \u003c48\u003e 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48\nRSP: 002b:00007fcf5c7b9038 EFLAGS: 00000246 ORIG_RAX: 0000000000000010\nRAX: ffffffffffffffda RBX: 00007fcf5bbb6160 RCX: 00007fcf5b98e929\nRDX: 0000000000000000 RSI: 00000000400448cb RDI: 0000000000000009\nRBP: 00007fcf5ba10b39 R08: 0000000000000000 R09: 0000000000000000\nR10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000\nR13: 0000000000000000 R14: 00007fcf5bbb6160 R15: 00007ffd6353d528\n \u003c/TASK\u003e\n\nAllocated by task 6535:\n kasan_save_stack mm/kasan/common.c:47 [inline]\n kasan_save_track+0x3e/0x80 mm/kasan/common.c:68\n poison_kmalloc_redzone mm/kasan/common.c:377 [inline]\n __kasan_kmalloc+0x93/0xb0 mm/kasan/common.c:394\n kasan_kmalloc include/linux/kasan.h:260 [inline]\n __kmalloc_cache_noprof+0x230/0x3d0 mm/slub.c:4359\n kmalloc_noprof include/linux/slab.h:905 [inline]\n kzalloc_noprof include/linux/slab.h:1039 [inline]\n vhci_open+0x57/0x360 drivers/bluetooth/hci_vhci.c:635\n misc_open+0x2bc/0x330 drivers/char/misc.c:161\n chrdev_open+0x4c9/0x5e0 fs/char_dev.c:414\n do_dentry_open+0xdf0/0x1970 fs/open.c:964\n vfs_open+0x3b/0x340 fs/open.c:1094\n do_open fs/namei.c:3887 [inline]\n path_openat+0x2ee5/0x3830 fs/name\n---truncated---",
