| CVE-2026-88385 | 2026-09-24 | N/A | ||
| Mini-XML 4.0.5 contains a memory leak vulnerability in mxml_load_data() during malformed XML parsing. Specially crafted XML input can cause text nodes allocated by mxmlNewText() to become unlinked before a parse error transfers control to the cleanup path. These orphaned nodes are not released, resulting in a persistent memory leak on each parsing attempt. Repeated attacker-controlled requests can cause cumulative memory exhaustion and denial of service. | ||||
| CVE-2026-94609 | 2026-09-24 | 8.8 High | ||
| authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an account with delegated permission to manage a group, group membership, or a user can grant superuser status to an account or assign an existing role to a group without holding the permissions that gate those privileges. Group hierarchy checks do not consistently account for superuser status inherited from ancestor groups, and role assignment to a group lacks the required authorization check. Only deployments that delegate these management capabilities to accounts that are not full administrators are affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2. | ||||
| CVE-2026-93545 | 1 X.org | 1 Libxi | 2026-09-24 | 6.5 Medium |
| An out-of-bounds read in libXi's XListInputDevices() in libXi before 1.8.4 could be used by malicious X servers to crash an attached X client. | ||||

| CVE-2026-94611 | 2026-09-24 | 8.1 High | ||
| authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, authentik API serializers return stored credentials when an account has view permission on an affected configuration, even when that account is not authorized to change the configuration or read its secrets. Affected configurations include one-time code delivery by mail or SMS, outbound provisioning targets, device trust integrations, identity sources, the Kubernetes outpost integration, applications using a client or shared secret, and applications using a proxy provider. Deployments are affected when view permission is granted to accounts that are not intended to read these credentials; deployments where every viewer is permitted to read them are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2. | ||||
| CVE-2026-78002 | 2 Redhat, Rsyslog | 3 Enterprise Linux, Rhui, Rsyslog | 2026-09-24 | 7.5 High |
| A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript `replace()` function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory corruption. Successful exploitation can lead to a denial of service (DoS) for the affected system. | ||||
| CVE-2026-19654 | 2 Redhat, Rsyslog | 4 Enterprise Linux, Enterprise Linux Eus, Rhui and 1 more | 2026-09-24 | 7.5 High |
| A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imptcp framing modes are not affected. | ||||
| CVE-2026-94612 | 2026-09-24 | 7.4 High | ||
| authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an authentik SAML Source verifies an assertion's signature and validity period but does not ensure that the identity provider issued the assertion for that Source or in response to a login request from that Source. The SAML Source also does not record already accepted assertions, allowing replay. An unauthenticated actor who possesses such a valid assertion can use an assertion intended for another service provider or reuse an earlier assertion to authenticate as the user named by the assertion. Only SAML Sources are affected; SAML Providers and other Source types are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2. | ||||
| CVE-2026-96512 | 2 Redhat, Sudo Project | 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more | 2026-09-24 | 7.8 High |
| A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the intended time window. Authentication is not bypassed; only the time-based authorization check is affected. | ||||
| CVE-2026-71576 | 1 Redhat | 1 Multicluster Globalhub | 2026-09-24 | 8.5 High |
| A flaw was found in multicluster-global-hub. The manager component improperly validates the source identity of incoming CloudEvents on Kafka status topics. A remote attacker, after compromising a managed hub and obtaining its Kafka client certificate, can manipulate the self-asserted source identity. This allows the attacker to falsify or delete critical data, such as compliance, inventory, and cluster health information, belonging to other hubs in the database. | ||||
| CVE-2026-66792 | 1 Redhat | 6 Acm, Advanced Cluster Management For Kubernetes, Multicluster Globalhub and 3 more | 2026-09-24 | 9.9 Critical |
| A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a user on a managed cluster to escalate their privileges by creating a Subscription with specific, crafted annotations. Successful exploitation grants the attacker the ability to deploy resources into any namespace with the elevated permissions of the controller's Service Account, potentially leading to unauthorized access and control over cluster resources. | ||||
| CVE-2026-93544 | 1 X.org | 1 Libxi | 2026-09-24 | 6.5 Medium |
| An out-of-bounds read in libXi's XI2 XIQueryDevice reply parsing in libXi before 1.8.4 can be used by a malicious X server to crash an attached X client. | ||||
| CVE-2026-94613 | 2026-09-24 | 7.5 High | ||
| authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an unauthenticated attacker can submit a malformed SAML message to an authentik deployment using SAML in either the identity-provider or SAML source role. The message can stop the worker handling /application/saml/* or /source/saml/*, causing the requests assigned to that worker to fail. Worker process termination and automatic restart do not destroy database-backed sessions, but continued malicious messages can cause a sustained share of legitimate traffic to fail. Other protocol implementations are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2. | ||||
| CVE-2026-93543 | 1 X.org | 1 Libxi | 2026-09-24 | 7.4 High |
| An out-of-bounds read in libXi's XI2 class parser in libXi before 1.8.4 could be used by malicious X servers to crash an attached X client. | ||||
| CVE-2026-79763 | 2026-09-24 | 5.3 Medium | ||
| Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 2.4.0 until 2.5.1, the POST /users/totp/disable and POST /users/totp/backup-codes endpoints accept the account password as the sole reauthentication factor after a 2.4.0 refactor regressed the two-factor check introduced for CVE-2026-45749. In src/backend/database/routes/user-totp-routes.ts, verifyTotpReauth returns success when bcrypt.compare validates the password, while each endpoint chooses password or totp_code as an interchangeable credential. An attacker who has a victim's authenticated session and knows the password can disable TOTP or regenerate and invalidate backup codes without an authenticator or valid second factor, weakening the account to single-factor authentication. This issue is fixed in version 2.5.1. | ||||
| CVE-2026-97521 | 1 Linux | 1 Linux Kernel | 2026-09-24 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: gfs2: fix quota init duplicate scan gfs2_quota_init() checks for duplicate quota_change IDs while holding qd_lock and the quota hash bucket bitlock. That path used gfs2_qd_search_bucket(), which takes a lockref reference via lockref_get_not_dead(). On PREEMPT_RT this may sleep, which is not allowed under the bucket bitlock, triggering "sleeping function called from invalid context". Use a no-ref bucket lookup in this path, then continue duplicate handling without taking a lockref there. Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper so lookup traversal stays in one place. This patch fixes a bug reported by syzbot. | ||||
| CVE-2026-97520 | 1 Linux | 1 Linux Kernel | 2026-09-24 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: gfs2: move quota_init qc iterator increment Move qc++ from the loop body into the for-loop increment expression in gfs2_quota_init(). This keeps iterator progression explicit and avoids mixing pointer advance with duplicate-slot handling in the loop body. | ||||
| CVE-2026-97519 | 1 Linux | 1 Linux Kernel | 2026-09-24 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix null pointer dereference in devcoredump cleanup In xe_devcoredump_snapshot_free(), ss->gt may be NULL when the snapshot was never fully populated (e.g., when cleanup is triggered without a prior capture). Guard the xe_guc_capture_put_matched_nodes() call with IS_ERR_OR_NULL() to prevent a null dereference. In xe_devcoredump_free(), the deferred work is only queued when a coredump is captured, so guard cancel_work_sync() with a check on coredump->captured. | ||||
| CVE-2026-97518 | 1 Linux | 1 Linux Kernel | 2026-09-24 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: reject duplicate wiphy cipher suite entries Duplicate entries in wiphy->cipher_suites do not describe any additional capability, but cfg80211 currently accepts them and leaves individual consumers to deal with them. One such consumer is the WEXT compatibility code, which appends a WEP key length for each WEP cipher entry it sees. Repeated WEP entries can therefore overflow the fixed iw_range::encoding_size array returned by SIOCGIWRANGE. Reject duplicate cipher suite entries in wiphy_register() instead. This keeps the cipher suite invariant in one place and makes malformed wiphy descriptions fail early with -EINVAL, rather than relying on a single cfg80211 user to handle duplicates correctly. | ||||
| CVE-2026-97517 | 1 Linux | 1 Linux Kernel | 2026-09-24 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: reject beacons with bad HE operation The HE operation element not only needs to be longer than the fixed part, but also have an appropriate size for the variable part inside of it. Check this. | ||||
