CVE-2026-119618 2026-11-11 N/A
Concurrent Execution using Shared Resource with Improper Synchronization vulnerability in Apache HTTP Server's mod_http2 in assign_headers() can lead to RCE. This issue affects Apache HTTP Server: from 2.4.55 through 2.4.70. Affected releases of mod_h2 from GitHub: from 2.0.8 through 2.0.42.
CVE-2026-88924 2 Gnome, Redhat 6 Gvfs, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-11 7 High
A flaw was found in the admin backend of gvfs. The privileged gvfsd-admin daemon changes the ownership of newly created private D-Bus sockets by calling the link-following chown() function on a pathname inside a user-controlled directory. A local attacker can exploit this via a Time-of-Check Time-of-Use (TOCTOU) race condition and exchange the socket pathname with a symbolic link pointing to an arbitrary root-owned file (such as /etc/pam.d/su). The daemon subsequently follows the symlink and changes the ownership of the targeted root-owned file to the attacker's user ID. This allows an authenticated local attacker to modify critical system files, leading to a full local privilege escalation to root.
CVE-2026-105566 1 Microsoft 23 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 20 more 2026-11-11 7 High
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Kernel allows an authorized attacker to elevate privileges locally.
CVE-2026-106137 2026-11-11 8.6 High
In affected versions of Progress® Telerik® UI for ASP.NET MVC `2012.2.710` through `2026.3.811`, ClassFactory updates a shared class dictionary without exclusive write protection and emits non-collectible dynamic assemblies that remain loaded for the AppDomain's lifetime. The dictionary lookup and insertion are not atomic, and case variations in aggregate descriptors can produce distinct retained types even though member resolution is case-insensitive. An unauthenticated remote attacker can exploit this if the application exposes an aggregation endpoint that is reachable without authentication, by submitting concurrent or repeated crafted requests. These requests may corrupt dictionary state or increase CPU and memory use, potentially degrading availability. The issue is fixed in version `2026.3.1015`.
CVE-2025-54506 2026-11-11 N/A
A time-of-check to time-of-use (TOCTOU) race condition in the AMD SEV Secure Encrypted Virtualization (SEV) firmware could allow an attacker with administrative privileges to bypass security checks on scatter lists, potentially resulting in loss of guest integrity.
CVE-2025-52537 2026-11-11 N/A
Improper access control within the AMD Secure Encrypted Virtualization (SEV) firmware could allow an attacker with administrative privileges to tamper with memory, potentially resulting in loss of guest memory integrity.
CVE-2026-123804 1 Supertokens 1 Supertokens 2026-11-11 6.8 Medium
SuperTokens Core is an open source authentication server. From 7.0.0 until 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1, createNewSession can resolve a primary user before unlinkAccounts detaches a login method and then insert the session after unlink has enumerated and revoked the existing sessions. A user who controls the linked login method can exploit this race to retain a signed, database-backed, refreshable session as the former primary identity after that method is unlinked; the session persists until expiry or explicit revocation. This issue is fixed in versions 11.0.9, 11.1.4, 11.2.4, 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1.
CVE-2026-102803 1 J2commerce.com 1 J2store Extension For Joomla 2026-11-11 N/A
Joomla Extension - j2commerce.com - Gift voucher and single-use coupon could pay for more than one order in J2Store 6.0.0 - 6.6.5 - A logged-in customer could redeem a single gift voucher, or a single-use coupon (`max_uses` / `max_customer_uses` = 1), on more than one order. By starting several checkout sessions and carrying each to the confirm step before submitting any of them, every order independently saw the voucher's full balance or the coupon's unused slot, because the balance/usage calculations and the final placement check both only looked at orders that had already left the "New" state.

CVE-2026-105017 1 Microsoft 23 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 20 more 2026-11-11 7 High
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Volume Shadow Copy allows an authorized attacker to elevate privileges locally.
CVE-2026-105545 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-11-11 7 High
An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.
CVE-2026-105546 1 Microsoft 23 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 20 more 2026-11-11 7 High
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Management Instrumentation allows an authorized attacker to elevate privileges locally.
CVE-2026-55950 1 Erlang 4 Erlang/otp, Erlang\/otp, Erlang\/ssl and 1 more 2026-11-11 5.9 Medium
Time-of-check Time-of-use (TOCTOU) race condition vulnerability in Erlang/OTP ssl (dtls_packet_demux module) allows an unauthenticated remote attacker to crash all active DTLS sessions on a listener. A DTLS server listener uses a single shared dtls_packet_demux gen_server process to route incoming UDP datagrams to the correct connection handler. When a DTLS client reconnects rapidly from the same source address and port (sending multiple ClientHello messages in quick succession), a race condition in the demux's internal gb_trees key-value store causes a {key_exists, {old, Client}} crash, terminating the demux process. Because the demux is shared across all DTLS associations on that listener, its crash immediately kills every active DTLS session, not just the attacker's. The attack is pre-authentication: the attacker only needs to send UDP datagrams containing valid ClientHello messages from the same source IP and port before the intermediate DOWN monitor message is processed by the gen_server. No credentials, no completed handshake, and no special configuration are required, and the crash can be repeated indefinitely to create a persistent denial of service for all clients of that listener. This vulnerability is associated with program file lib/ssl/src/dtls_packet_demux.erl. This issue affects OTP from OTP 25.3 before OTP 27.3.4.14, OTP 28.5.0.3, and OTP 29.0.3, corresponding to ssl from 10.9 before 11.2.12.10, 11.6.0.3, and 11.7.3.
CVE-2026-93683 1 Redhat 3 Enterprise Linux, Openshift, Openstack 2026-11-11 6.4 Medium
A flaw was found in the DPDK vhost library. When handling a virtio indirect descriptor table, the host reads the table length more than once from guest memory and can allocate a host copy before validating that length. A guest that changes the length between those reads, or that supplies an out-of-range next index on a small host copy in the vDPA relay path, can cause the host vhost process to walk past the validated mapping or heap copy. That can crash or disrupt the vhost process. Out-of-bounds bytes are consumed as descriptor fields for GPA translation and are not returned to the guest as payload. This is a residual issue in the non-contiguous indirect descriptor copy path introduced as part of the CVE-2018-1059 fix.
CVE-2026-86848 1 Redhat 3 Enterprise Linux, Openshift, Openstack 2026-11-11 8.8 High
A flaw was found in DPDK lib/vhost vhost-crypto. The indirect-descriptor snapshot double-fetches a guest descriptor next index, allowing a malicious guest to cause an out-of-bounds access in the host backend.
CVE-2026-86562 1 Redhat 3 Enterprise Linux, Openshift, Openstack 2026-11-11 7.8 High
A flaw was found in DPDK lib/vhost. A TOCTOU double-fetch of control-queue descriptors allows a heap buffer overflow with attacker-controlled content in the VDUSE control-queue handler.
CVE-2026-91205 1 Redhat 1 Enterprise Linux 2026-11-11 6 Medium
A flaw was found in cockpit-files. A local unprivileged attacker can exploit a race condition during directory creation with owner assignment. By controlling a writable parent directory, the attacker can replace a newly created directory with a symbolic link (symlink) before the ownership change operation (chown) is applied. This allows the attacker to redirect the ownership change to an arbitrary file, potentially leading to information disclosure or unauthorized modification of sensitive files.
CVE-2026-112201 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-11-11 4.8 Medium
A flaw was found in the login-failure storage component of Keycloak, the identity and access management solution. This issue specifically affects deployments using MySQL or MariaDB databases in a multi-node configuration. When multiple failed login attempts occur simultaneously for the same account, a synchronization error can cause the system to enter a repetitive loop that locks the user's record in the database. This results in legitimate login attempts for that user being blocked and failing with an error. Furthermore, because some failures are not correctly recorded during this loop, the system's brute-force protection may not accurately count all failed attempts.
