CVE-2026-101311 (GCVE-0-2026-101311)

Vulnerability from cvelistv5 – Published: 2026-10-15 07:18 – Updated: 2026-10-16 03:56
VLAI
Title
Multiple vulnerabilities in bhyve device models
Summary
The framebuffer device model's maximum resolution constants were duplicated between the framebuffer and RFB modules and had gotten out of sync. Additionally, writes to the framebuffer BAR could set arbitrary width and height values without validation, and the framebuffer BAR I/O and RFB rendering threads were not synchronized. A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox.

CVE-2026-101310 (GCVE-0-2026-101310)

Vulnerability from cvelistv5 – Published: 2026-10-15 07:18 – Updated: 2026-10-16 03:56
VLAI
Title
Multiple vulnerabilities in bhyve device models
Summary
The HDA audio device model did not check for zero-length Buffer Descriptor List (BDL) entries when starting a stream. A zero-length entry caused an out-of-bounds read or write during DMA transfer processing. BDL fields were also subject to modification by the guest after validation. A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox.

Title
Multiple vulnerabilities in bhyve device models
Summary
The xHCI (USB 3) device model did not validate or save the event ring size provided by the guest. The size was re-read from guest memory on each use, and Transfer Request Block (TRB) fields were loaded without protection against concurrent modification by the guest. This race condition could be triggered by a guest running malicious, privileged code. A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox.

CVE-2026-101041 (GCVE-0-2026-101041)

Title
Vulnerability-Lookup - Race Condition in Account Recovery Token Consumption Allows Password Takeover
Summary
The account recovery (password reset) functionality in the vulnerability-lookup web application contains a time-of-check-to-time-of-use (TOCTOU) race condition in the consumption of single-use recovery tokens. The original implementation verified the token nonce against the stored digest and then consumed (cleared) it in separate database operations. Two concurrent HTTP requests presenting the same valid recovery token could both pass the verification check before either transaction committed, allowing both to set their own password on the target account. The last transaction to commit overwrites the first, enabling an attacker who possesses a valid recovery token to replace the legitimate user's password with one of their choosing. A secondary defect in the same endpoint (confirm_account) allowed a valid recovery link to be used to set an empty or trivially short password (e.g., three characters). The view handler performed only a manual equality comparison between the two password fields and never invoked the form's validation logic, bypassing the intended minimum-length and complexity constraints. The affected component is the user account recovery endpoint (/user/confirm_account/<token>) and the associated token verification and consumption logic in the User model (website/models/user.py) and the view layer (website/web/views/user.py).

Fix summary

The non-atomic check-then-consume pattern is replaced with a single conditional UPDATE statement (compare-and-set) that atomically verifies the stored SHA-256 nonce digest, updates the password hash, sets is_confirmed, and clears the token in one database operation. Only the first transaction to commit succeeds; all concurrent attempts match zero rows and are rejected with an error. The view now calls form.validate() before processing the password change, enforcing the form's length and equality validators. The dead consume_account_token() method is removed to eliminate the non-atomic consumption path entirely.

Patch summary

Added reset_password_with_account_token() to the User model performing a single conditional UPDATE (WHERE id = ? AND account_token_digest = sha256(nonce)) that sets pwdhash, is_confirmed=True, and account_token_digest=None atomically. Removed the separate consume_account_token() method. Changed the confirm_account view to call form.validate() instead of only comparing password1 and password2 manually. Introduced a _account_token_digest() static helper to centralize the SHA-256 computation (previously three inline calls). Removed synchronize_session=False from the UPDATE execution options so the ORM session stays consistent. Added regression tests for concurrent token consumption (two threads, barrier-synchronized) and for rejection of passwords that fail form validation (empty, three-character, mismatched).

CVSS rationale

AV:N: the recovery endpoint is reachable over the network. AC:H: exploiting the race condition requires precise timing of two concurrent requests, making the attack condition high complexity. AT:N: no active user interaction or deception is required beyond possessing a valid token. PR:N: no prior authentication is needed; the recovery token itself is the credential. UI:N: no user interaction is required. VC:N: the vulnerability does not directly expose confidential data. VI:H: the integrity of the user's password (a critical credential) is directly compromised. VA:N: no availability impact. SC:N: the impact is confined to the vulnerable component. SI:H: the integrity of the user's account (password, confirmation state) is compromised, affecting the user's ability to access their own account. SA:N: no security-authority impact.

Weakness rationale
  • CWE-362 The primary defect is a TOCTOU race: the token nonce is verified and then consumed in separate operations, allowing two concurrent transactions to both pass verification before either commits. The fix replaces this with an atomic compare-and-set UPDATE, confirming the race condition as the root cause.
  • CWE-20 The confirm_account view never called form.validate() on POST, so the form's minimum-length and equality validators were bypassed. A valid recovery link alone permitted setting an empty or three-character password. The fix adds the form.validate() call before processing.
Attack pattern rationale
  • CAPEC-111 The attacker exploits the window between token verification and token consumption by issuing a concurrent request with the same token. Both requests pass the check; the last to commit overwrites the first's password. This is a textbook race-condition attack on a shared resource (the single-use token). CAPEC-111 is the closest available pattern; no CAPEC specifically covers TOCTOU on database-level token consumption, so this is the best match.
Assumptions to verify
  • The product version and exact release boundary are not specified in the patch metadata; the affected version range is recorded as unspecified.
  • The CAPEC-111 mapping is the closest available pattern for a database-level TOCTOU race on a single-use token; no CAPEC specifically describes concurrent compare-and-set exploitation, so this is the best available match.
  • The CVSS AC:H reflects the race-condition aspect; the missing-validation aspect alone would be AC:L, but the patch set is treated as one vulnerability per the caller's instruction.
  • The vendor is not explicitly identified in the metadata; the GitHub repository name 'vulnerability-lookup' is used as the product identifier.
  • No specific authentication or deployment preconditions beyond possession of a valid recovery token are stated in the patch; the token is assumed to be delivered out-of-band (e.g., email).
  • The Co-Authored-By line for Claude Fable 5.1 is treated as a remediation developer credit per the metadata's remediation_developers list; no finder or reporter is identified in the supplied evidence.

Changed the confirm_account view to call form.validate() instead of only comparing password1 and password2 manually. Introduced a _account_token_digest() static helper to centralize the SHA-256 computation (previously three inline calls). Removed synchronize_session=False from the UPDATE execution options so the ORM session stays consistent.

CVE-2026-100546 (GCVE-0-2026-100546)

Title
OpenClaw 2026.7.2 before 2026.9.2 Authentication Bypass via Voice Transcript
Summary
OpenClaw (npm package `openclaw`) versions >= 2026.7.2 and < 2026.9.2 contain a race condition in the Discord realtime voice transcript path. Concurrent control-classified voice transcripts could consume speaker context belonging to another participant after an asynchronous control check, causing a transcript to inherit another speaker's owner status. In Discord agent-proxy voice sessions using the affected realtime control path, an utterance from a non-owner participant could reach the downstream agent boundary marked as owner, so owner-sensitive behavior is applied to the wrong speaker. Exploitation depends on concurrent transcript timing and on the tools and commands available to the affected agent. The issue is fixed in 2026.9.2; as a workaround, disable Discord realtime voice for agents that distinguish owner and non-owner senders.

Title
Nezha Monitoring: Whole-instance DoS in Nezha dashboard: a member can crash the process for every tenant
Summary
Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From 2.2.7 until 2.2.11, ServiceSentinel.worker in service/singleton/servicesentinel.go checked an owned service under servicesLock and later dereferenced pointer-valued serviceStatusToday and serviceCurrentStatusData entries under serviceResponseDataStoreLock without revalidating that ServiceSentinel.Delete had not removed them. A RoleMember could concurrently report TCP or ICMP results through the member's own agent and delete the same owned service, causing a nil pointer dereference. Because the gRPC server had no recovery interceptor, the worker panic terminated the whole dashboard process and disrupted every tenant's web interface, REST API, and agent connections. The issue affects availability only and does not disclose or modify data. This issue is fixed in versions 2.2.11 and 2.3.0.

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.
