GHSA-FR68-GVH3-4QHV

Vulnerability from github – Published: 2026-04-22 15:31 – Updated: 2026-07-14 15:31

Details

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

ext4: publish jinode after initialization

ext4_inode_attach_jinode() publishes ei->jinode to concurrent users. It used to set ei->jinode before jbd2_journal_init_jbd_inode(), allowing a reader to observe a non-NULL jinode with i_vfs_inode still unset.

The fast commit flush path can then pass this jinode to jbd2_wait_inode_data(), which dereferences i_vfs_inode->i_mapping and may crash.

Below is the crash I observe:

Fix this by initializing the jbd2_inode first. Use smp_wmb() and WRITE_ONCE() to publish ei->jinode after initialization. Readers use READ_ONCE() to fetch the pointer.

GHSA-FRC9-XCW3-3R8J

Vulnerability from github – Published: 2025-10-03 21:30 – Updated: 2025-10-08 21:30

Details

A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack.

We have already fixed the vulnerability in the following versions: QTS 5.2.6.3195 build 20250715 and later QuTS hero h5.2.6.3195 build 20250715 and later

GHSA-FRG3-QCJH-FVR9

Vulnerability from github – Published: 2022-05-24 17:01 – Updated: 2023-02-02 21:33

Details

A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.

Severity

5.5 (Medium)

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-05 18:14

Details

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

RDMA/cma: Fix workqueue crash in cma_netevent_work_handler

struct rdma_cm_id has member "struct work_struct net_work" that is reused for enqueuing cma_netevent_work_handler()s onto cma_wq.

Below crash[1] can occur if more than one call to cma_netevent_callback() occurs in quick succession, which further enqueues cma_netevent_work_handler()s for the same rdma_cm_id, overwriting any previously queued work-item(s) that was just scheduled to run i.e. there is no guarantee the queued work item may run between two successive calls to cma_netevent_callback() and the 2nd INIT_WORK would overwrite the 1st work item (for the same rdma_cm_id), despite grabbing id_table_lock during enqueue.

Also drgn analysis [2] indicates the work item was likely overwritten.

Fix this by moving the INIT_WORK() to __rdma_create_id(), so that it doesn't race with any existing queue_work() or its worker thread.

[1] Trimmed crash stack:

BUG: kernel NULL pointer dereference, address: 0000000000000008 kworker/u256:6 ... 6.12.0-0... Workqueue: cma_netevent_work_handler [rdma_cm] (rdma_cm) RIP: 0010:process_one_work+0xba/0x31a Call Trace: worker_thread+0x266/0x3a0 kthread+0xcf/0x100 ret_from_fork+0x31/0x50 ret_from_fork_asm+0x1a/0x30 =============================================

[2] drgn crash analysis:

trace = prog.crashed_thread().stack_trace() trace (0) crash_setup_regs (./arch/x86/include/asm/kexec.h:111:15) (1) __crash_kexec (kernel/crash_core.c:122:4) (2) panic (kernel/panic.c:399:3) (3) oops_end (arch/x86/kernel/dumpstack.c:382:3) ... (8) process_one_work (kernel/workqueue.c:3168:2) (9) process_scheduled_works (kernel/workqueue.c:3310:3) (10) worker_thread (kernel/workqueue.c:3391:4) (11) kthread (kernel/kthread.c:389:9)

Line workqueue.c:3168 for this kernel version is in process_one_work(): 3168 strscpy(worker->desc, pwq->wq->name, WORKER_DESC_LEN);

trace[8]["work"] (struct work_struct )0xffff92577d0a21d8 = { .data = (atomic_long_t){ .counter = (s64)536870912, <=== Note }, .entry = (struct list_head){ .next = (struct list_head )0xffff924d075924c0, .prev = (struct list_head )0xffff924d075924c0, }, .func = (work_func_t)cma_netevent_work_handler+0x0 = 0xffffffffc2cec280, }

Suspicion is that pwq is NULL:

trace[8]["pwq"] (struct pool_workqueue *)

In process_one_work(), pwq is assigned from: struct pool_workqueue *pwq = get_work_pwq(work);

and get_work_pwq() is: static struct pool_workqueue get_work_pwq(struct work_struct work) { unsigned long data = atomic_long_read(&work->data);

if (data & WORK_STRUCT_PWQ)
    return work_struct_pwq(data);
else
    return NULL;

}

WORK_STRUCT_PWQ is 0x4:

print(repr(prog['WORK_STRUCT_PWQ'])) Object(prog, 'enum work_flags', value=4)

But work->data is 536870912 which is 0x20000000. So, get_work_pwq() returns NULL and we crash in process_one_work(): 3168 strscpy(worker->desc, pwq->wq->name, WORKER_DESC_LEN); =============================================

Severity

5.5 (Medium)

Vulnerability from github – Published: 2022-09-16 21:59 – Updated: 2022-09-19 19:07

Summary

TensorFlow vulnerable to null dereference on MLIR on empty function attributes

Details

Impact

When mlir::tfg::ConvertGenericFunctionToFunctionDef is given empty function attributes, it gives a null dereference.

// Import the function attributes with a `tf.` prefix to match the current
// infrastructure expectations.
for (const auto& namedAttr : func.attr()) {
  const std::string& name = "tf." + namedAttr.first;
  const AttrValue& tf_attr = namedAttr.second;
  TF_ASSIGN_OR_RETURN(Attribute attr,
                      ConvertAttributeValue(tf_attr, builder, tfgDialect));
  attrs.append(name, attr);
}

If namedAttr.first is empty, it will crash.

Patches

We have patched the issue in GitHub commit 1cf45b831eeb0cab8655c9c7c5d06ec6f45fc41b.

The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
