CVE-2026-20445 2 Google, Mediatek 24 Android, Mt6835, Mt6855 and 21 more 2026-04-16 4.4 Medium
In MDDP, there is a possible system crash due to a race condition. This could lead to local denial of service if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10289875; Issue ID: MSV-5184.
CVE-2026-27750 2 Avira, Gen Digital 3 Avira Internet Security Suite, Internet Security, Avira Internet Security 2026-04-16 7.8 High
Avira Internet Security contains a time-of-check time-of-use (TOCTOU) vulnerability in the Optimizer component. A privileged service running as SYSTEM identifies directories for cleanup during a scan phase and subsequently deletes them during a separate cleanup phase without revalidating the target path. A local attacker can replace a previously scanned directory with a junction or reparse point before deletion occurs, causing the privileged process to delete an unintended system location. This may result in deletion of protected files or directories and can lead to local privilege escalation, denial of service, or system integrity compromise depending on the affected target.
CVE-2026-26017 1 Coredns.io 1 Coredns 2026-04-16 7.7 High
CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a logical vulnerability in CoreDNS allows DNS access controls to be bypassed due to the default execution order of plugins. Security plugins such as acl are evaluated before the rewrite plugin, resulting in a Time-of-Check Time-of-Use (TOCTOU) flaw. This issue has been patched in version 1.14.2.
CVE-2026-28689 1 Imagemagick 1 Imagemagick 2026-04-16 6.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, domain="path" authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
CVE-2026-31824 1 Sylius 1 Sylius 2026-04-16 8.2 High
Sylius is an Open Source eCommerce Framework on Symfony. A Time-of-Check To Time-of-Use (TOCTOU) race condition was discovered in the promotion usage limit enforcement. The same class of vulnerability affects the promotion usage limit (the global used counter on Promotion entities), coupon usage limit (the global used counter on PromotionCoupon entities), and coupon per-customer usage limit (the per-customer redemption count on PromotionCoupon entities). In all three cases, the eligibility check reads the used counter (or order count) from an in-memory Doctrine entity during validation, while the actual usage increment in OrderPromotionsUsageModifier happens later during order completion — with no database-level locking or atomic operations between the two phases. Because Doctrine flushes an absolute value (SET used = 1) rather than an atomic increment (SET used = used + 1), and because the affected entities lack optimistic locking, concurrent requests all read the same stale usage counts and pass the eligibility checks simultaneously. An attacker can exploit this by preparing multiple carts with the same limited-use promotion or coupon and firing simultaneous PATCH /api/v2/shop/orders/{token}/complete requests. All requests pass the usage limit checks and complete successfully, allowing a single-use promotion or coupon to be redeemed an arbitrary number of times. The per-customer limit can be bypassed in the same way by a single customer completing multiple orders concurrently. No authentication is required to exploit this vulnerability. This may lead to direct financial loss through unlimited redemption of limited-use promotions and discount coupons. The issue is fixed in versions: 1.9.12, 1.10.16, 1.11.17, 1.12.23, 1.13.15, 1.14.18, 2.0.16, 2.1.12, 2.2.3 and above.
CVE-2026-20816 1 Microsoft 23 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 20 more 2026-04-16 7.8 High

CVE-2026-1035 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more 2026-04-16 3.1 Low
A flaw was found in the Keycloak server during refresh token processing, specifically in the TokenManager class responsible for enforcing refresh token reuse policies. When strict refresh token rotation is enabled, the validation and update of refresh token usage are not performed atomically. This allows concurrent refresh requests to bypass single-use enforcement and issue multiple access tokens from the same refresh token. As a result, Keycloak’s refresh token rotation hardening can be undermined.
CVE-2026-26224 1 Intego 1 Log Reporter 2026-04-16 N/A
Intego Log Reporter, a macOS diagnostic utility bundled with Intego security products that collects system and application logs for support analysis, contains a local privilege escalation vulnerability. A root-executed diagnostic script creates and writes files in /tmp without enforcing secure directory handling, introducing a time-of-check to time-of-use (TOCTOU) race condition. A local unprivileged user can exploit a symlink-based race condition to cause arbitrary file writes to privileged system locations, resulting in privilege escalation to root.
CVE-2003-0813 1 Microsoft 5 Windows 2000, Windows 98, Windows Nt and 2 more 2026-04-16 N/A
A multi-threaded race condition in the Windows RPC DCOM functionality with the MS03-039 patch installed allows remote attackers to cause a denial of service (crash or reboot) by causing two threads to process the same RPC request, which causes one thread to use memory after it has been freed, a different vulnerability than CVE-2003-0352 (Blaster/Nachi), CVE-2003-0715, and CVE-2003-0528, and as demonstrated by certain exploits against those vulnerabilities.

CVE-2025-32784 2026-04-15 N/A
conda-forge-webservices is the web app deployed to run conda-forge admin commands and linting. In versions prior to 2025.4.10, a race condition vulnerability has been identified in the conda-forge-webservices component used within the shared build infrastructure. This vulnerability, categorized as a Time-of-Check to Time-of-Use (TOCTOU) issue, can be exploited to introduce unauthorized modifications to build artifacts stored in the cf-staging Anaconda channel. Exploitation may result in the unauthorized publication of malicious artifacts to the production conda-forge channel. The core vulnerability results from the absence of atomicity between the hash validation and the artifact copy operation. This gap allows an attacker, with access to the cf-staging token, to overwrite the validated artifact with a malicious version immediately after hash verification, but before the copy action is executed. As the cf-staging channel permits artifact overwrites, such an operation can be carried out using the anaconda upload --force command. This vulnerability is fixed in 2025.4.10.
CVE-2025-23279 1 Nvidia 1 Gpu Display Driver 2026-04-15 7 High
NVIDIA .run Installer for Linux and Solaris contains a vulnerability where an attacker could use a race condition to escalate privileges. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, denial of service, or data tampering.
CVE-2024-37181 1 Intel 1 Neural Compressor Software 2026-04-15 2.6 Low
Time-of-check time-of-use race condition in some Intel(R) Neural Compressor software before version v3.0 may allow an authenticated user to potentially enable information disclosure via adjacent access.
CVE-2025-27725 1 Intel 1 Acat Software 2026-04-15 4.4 Medium
Time-of-check time-of-use race condition for some ACAT before version 3.13 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
