CWE-362

Allowed-with-Review

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Abstraction: Class · Status: Draft

The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.

3189 vulnerabilities reference this CWE, most recent first.

GHSA-M4CC-C4JQ-H2WR

Details

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

net/sched: ets: Always remove class from active list before deleting in ets_qdisc_change

zdi-disclosures@trendmicro.com says:

The vulnerability is a race condition between ets_qdisc_dequeue and ets_qdisc_change. It leads to UAF on struct Qdisc object. Attacker requires the capability to create new user and network namespace in order to trigger the bug. See my additional commentary at the end of the analysis.

Analysis:

static int ets_qdisc_change(struct Qdisc sch, struct nlattr opt, struct netlink_ext_ack *extack) { ...

  // (1) this lock is preventing .change handler (`ets_qdisc_change`)
  //to race with .dequeue handler (`ets_qdisc_dequeue`)
  sch_tree_lock(sch);

  for (i = nbands; i < oldbands; i++) {
          if (i >= q->nstrict && q->classes[i].qdisc->q.qlen)
                  list_del_init(&q->classes[i].alist);
          qdisc_purge_queue(q->classes[i].qdisc);
  }

  WRITE_ONCE(q->nbands, nbands);
  for (i = nstrict; i < q->nstrict; i++) {
          if (q->classes[i].qdisc->q.qlen) {
          // (2) the class is added to the q->active
                  list_add_tail(&q->classes[i].alist, &q->active);
                  q->classes[i].deficit = quanta[i];
          }
  }
  WRITE_ONCE(q->nstrict, nstrict);
  memcpy(q->prio2band, priomap, sizeof(priomap));

  for (i = 0; i < q->nbands; i++)
          WRITE_ONCE(q->classes[i].quantum, quanta[i]);

  for (i = oldbands; i < q->nbands; i++) {
          q->classes[i].qdisc = queues[i];
          if (q->classes[i].qdisc != &noop_qdisc)
                  qdisc_hash_add(q->classes[i].qdisc, true);
  }

  // (3) the qdisc is unlocked, now dequeue can be called in parallel
  // to the rest of .change handler
  sch_tree_unlock(sch);

  ets_offload_change(sch);
  for (i = q->nbands; i < oldbands; i++) {
      // (4) we're reducing the refcount for our class's qdisc and
      //  freeing it
          qdisc_put(q->classes[i].qdisc);
      // (5) If we call .dequeue between (4) and (5), we will have
      // a strong UAF and we can control RIP
          q->classes[i].qdisc = NULL;
          WRITE_ONCE(q->classes[i].quantum, 0);
          q->classes[i].deficit = 0;
          gnet_stats_basic_sync_init(&q->classes[i].bstats);
          memset(&q->classes[i].qstats, 0, sizeof(q->classes[i].qstats));
  }
  return 0;

}

Comment: This happens because some of the classes have their qdiscs assigned to NULL, but remain in the active list. This commit fixes this issue by always removing the class from the active list before deleting and freeing its associated qdisc

Vulnerability from github – Published: 2024-08-17 09:30 – Updated: 2025-09-29 15:30

Details

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

erofs: fix race in z_erofs_get_gbuf()

In z_erofs_get_gbuf(), the current task may be migrated to another CPU between z_erofs_gbuf_id() and spin_lock(&gbuf->lock).

Therefore, z_erofs_put_gbuf() will trigger the following issue which was found by stress test:

Mitigation
Architecture and Design

In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.

Mitigation
Architecture and Design

Use thread-safe capabilities such as the data access abstraction in Spring.

Mitigation
Architecture and Design
  • Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
  • Additionally, this will minimize the amount of synchronization necessary and may even help to reduce the likelihood of a denial of service where an attacker may be able to repeatedly trigger a critical section (CWE-400).
Mitigation
Implementation

When using multithreading and operating on shared variables, only use thread-safe functions.

Mitigation
Implementation

Use atomic operations on shared variables. Be wary of innocent-looking constructs such as "x++". This may appear atomic at the code layer, but it is actually non-atomic at the instruction layer, since it involves a read, followed by a computation, followed by a write.

Mitigation
Implementation

Use a mutex if available, but be sure to avoid related weaknesses such as CWE-412.

Mitigation
Implementation

Avoid double-checked locking (CWE-609) and other implementation errors that arise when trying to avoid the overhead of synchronization.

Mitigation
Implementation

Disable interrupts or signals over critical parts of the code, but also make sure that the code does not go into a large or infinite loop.

Mitigation
Implementation

Use the volatile type modifier for critical variables to avoid unexpected compiler optimization or reordering. This does not necessarily solve the synchronization problem, but it can help.

Mitigation MIT-17
Architecture and Design Operation

Strategy: Environment Hardening

Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.

CAPEC-26: Leveraging Race Conditions

The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.

CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions

This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
