RFCOMM session-disconnect race leaks session/L2CAP and denies further RFCOMM service in Zephyr Bluetooth Classic

A race condition in the Zephyr Bluetooth Classic RFCOMM host stack (subsys/bluetooth/host/classic/rfcomm.c) mishandles a simultaneous bidirectional session disconnect. When the local device has initiated a session teardown (state BT_RFCOMM_STATE_DISCONNECTING, DISC sent, RTX timer armed) and the connected peer concurrently sends its own DISC frame for dlci 0, rfcomm_handle_disc() invokes rfcomm_session_disconnected(), which unconditionally forced the session to BT_RFCOMM_STATE_DISCONNECTED without ever calling bt_l2cap_chan_disconnect(). Because the recovery timer was also cancelled and a later UA is ignored in the DISCONNECTED state, the session becomes permanently wedged: the underlying L2CAP channel is never released and the session slot in the fixed bt_rfcomm_pool[CONFIG_BT_MAX_CONN] array is never reclaimed (its conn pointer stays set). Subsequent bt_rfcomm_dlc_connect() calls on that connection fail with -EINVAL due to the invalid session state, so RFCOMM service is denied for that peer, and repeated occurrences can exhaust the session pool. The DISC frame is peer-controlled over the air, but exploitation requires the peer's DISC to collide with a local-initiated disconnect (a high-complexity timing race). Impact is availability/resource-leak only; there is no memory-safety, confidentiality, or integrity consequence. The defect shipped in released versions (present in v4.4.0 and earlier). The fix only transitions to DISCONNECTED when the session is not already in DISCONNECTING, preserving the proper L2CAP teardown path.

antlr ANTLR4 Maven Plugin GrammarDependencies.java ObjectInputStream.readObject toctou

A flaw has been found in antlr ANTLR4 up to 4.13.2. This affects the function ObjectInputStream.readObject of the file antlr4-maven-plugin/src/main/java/org/antlr/mojo/antlr4/GrammarDependencies.java of the component Maven Plugin. This manipulation causes time-of-check time-of-use. The attack is restricted to local execution. A high degree of complexity is needed for the attack. It is indicated that the exploitability is difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

um: Fix potential race condition in TLB sync

In the Linux kernel, the following vulnerability has been resolved: um: Fix potential race condition in TLB sync During the TLB sync, we need to traverse and modify the page table, so we should hold the page table lock. Since full SMP support for threads within the same process is still missing, let's disable the split page table lock for simplicity.

Iptanus File Upload < 5.1.7 - File Overwrite via Race Condition

The Iptanus File Upload WordPress plugin before 5.1.7 does not implement proper file handling when the duplicatepolicy setting is configured to "maintain both." Due to a Time-of-Check to Time-of-Use (TOCTOU) race condition between the file existence check and the actual file write operation, an authenticated attacker can overwrite files uploaded by other users.

Rockwell Automation FactoryTalk Historian Site Edition - Authentication Bypass

An authentication bypass security issue exists within FactoryTalk Historian Site Edition. By continually sending requests to the login endpoint, an attacker may obtain a valid authentication token.

Race Condition in Dell Display and Peripheral Manager Enables Local Privilege Escalation

Dell Display and Peripheral Manager (DDPM Mac), versions prior to 2.3, contain a Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

NocoDB: OAuth Authorization Code Race Condition

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, two concurrent token-exchange requests using the same OAuth authorization code could each mint a distinct valid (access_token, refresh_token) pair, breaking the single-use guarantee that PKCE relies on. This vulnerability is fixed in 2026.05.1.

OliveTin has a Concurrent Template Parsing Race Condition which Leads to Cross-Request Command Contamination

OliveTin gives access to predefined shell commands from a web interface. In versions 3000.0.0 and prior, the template engine uses a single shared text/template.Template instance (tpl package-level variable in service/internal/tpl/templates.go) across all goroutines. Every action execution calls tpl.Parse(source) followed by t.Execute() on this shared instance with no synchronization. When two or more actions execute concurrently (which is the normal case — each ExecRequest spawns a goroutine), a race condition occurs: one goroutine's Parse overwrites the template tree while another goroutine is calling Execute, causing cross-user command contamination, Go runtime panic, and incorrect command execution. This issue has been resolved in version 3000.13.0.

Filament: Multi-factor authentication (app) recovery codes can still be used multiple times via concurrent submission

Filament is a collection of full-stack components for accelerated Laravel development. From 4.0.0 until 4.11.5 and 5.6.5, a flaw in the handling of recovery codes for app-based multi-factor authentication allows the same recovery code to be reused via concurrent submission. This issue does not affect email-based MFA. It also only applies when recovery codes are enabled. If an attacker gains access to both the user's password and their recovery codes, they get two authenticated sessions per recovery code burned instead of one, or more if they batch the parallel submissions wider, materially extending the attacker's window of access compared to what the single-use guarantee implies. This vulnerability is fixed in 4.11.5 and 5.6.5.

pam_usb: Missing O_EXCL on pad temp file creation allows concurrent update race

pam_usb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open() without the O_EXCL flag. Without O_EXCL, the create operation is not atomic: two concurrent processes racing to update the same pad may both succeed in opening the file, with the second write silently overwriting the first. The one-time pad is the core replay-prevention mechanism of pam_usb. A successful race could result in the stored pad value diverging from what either process expected, potentially causing authentication failures or, in a precisely timed attack, creating a window for pad reuse. This issue has been fixed in version 0.9.2.

chromium-browser: chromium-browser: Inappropriate implementation in Updater

Race in Updater in Google Chrome on Mac prior to 149.0.7827.155 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)

Android NFC Use-After-Free Enables Local Privilege Escalation

In Nfc::eventCallback() of Nfc.h, there is a possible use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Open WebUI: LDAP and OAuth First-User Race Condition Allows Multiple Admin Accounts

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the LDAP and OAuth authentication flows use a TOCTOU (Time-of-Check-Time-of-Use) pattern for first-user admin role assignment. The regular signup handler (signup_handler in auths.py, line 663) was explicitly patched to prevent this race with the comment "Insert with default role first to avoid TOCTOU race", but the LDAP and OAuth code paths were never updated with the same fix. This vulnerability is fixed in 0.9.0.

x86 HVM I/O port list traversal

HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model (via XEN_DOMCTL_ioport_mapping), and hence the linked list used may changed at any time. Traversal of those lists (while handling guest I/O port accesses) therefore needs synchronizing with updates, which was missing so far.

In createSessionInternal of PackageInstallerService.java, there is a possible method to remove a DPC app from a managed device without DO consent due to desync from persistence. This could lead to local escalation of privilege if a user can install a malicious app with no additional execution privileges needed. User interaction is needed for exploitation.
