| CVE-2026-89755 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: mm/migrate_device: clear stale mapping after freeing swapcache __migrate_device_pages() reads the folio mapping before calling folio_free_swap(). When folio_free_swap() succeeds, the folio is removed from the swap cache, but the saved mapping still points to swap_space. Passing the stale mapping to folio_migrate_mapping() makes it use the mapped-folio path for a folio that is no longer in swapcache. It can then operate on swap_space.i_pages with invalid reference accounting, eventually triggering a folio reference count BUG. After a successful split, nr still contains the number of pages in the original large folio, although each resulting page is now a separate order-0 folio. Reset nr to 1 so each split folio is processed separately, including its own swapcache removal and mapping lookup. Refresh the saved mapping after folio_free_swap() so the current folio state is used during migration. | ||||
| CVE-2026-80668 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_expect: use conntrack GC to reap expectations This patch replaces the timer API by GC worker approach for expectations, as it already happened in many other subsystems. Use the existing conntrack GC worker to iterate over the local list of expectations in the master conntrack to reap expired expectations. Check IPS_HELPER_BIT to run GC for expectations, set it on for nft_ct expectation which nevers sets it. Hold the expectation spinlock while iterating over the master conntrack expectation list to synchronize with nf_ct_remove_expectations(). This also performs runtime packet path garbage collection through the expectation insertion and lookup functions while walking over one of the chains of the global expectation hashtables. Unconfirmed conntrack entries are skipped since ct->ext can be reallocated and dying are skipped since those will be gone soon. Set on IPS_HELPER_BIT if the helper ct extension is added, then the new GC worker does not need to bump the ct refcount to check if the ct->ext helper is available. This removes the extra bump on the refcount for expectation timers, this allows to remove several nf_ct_expect_put() calls after the unlink, after this update only refcount remains at 1 while on the expectation hashes. This patch implicitly addresses a race with the existing timer API allowing an expectation to access a stale exp->master pointer which has been already released when expectation removal loses races with an expiring timer, ie. timer_del() reporting false. Add a new NF_CT_EXPECT_DEAD flag to reap this expectation via GC. This is needed by nf_conntrack_unexpect_related() which is called in error paths to invalidate newly created expectations that has been added into the hashes. These expectactions cannot be inmediately released as GC or nf_ct_remove_expectations() could race to make it. On expectation insert, the runtime GC reaps stale expectations before checking the expectation limit set by policy. Set current timestamp in nf_ct_expect_alloc(), then add the expectation policy timeout (or custom timeout specified added on top of this) to specify the expectation lifetime. | ||||
| CVE-2026-107602 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the SAML 1.1 XML parsing logic of Keycloak, an open-source identity and access management solution. The issue occurs when the parser encounters unexpected elements within a security token's key information section, causing the processing thread to enter an infinite loop. An unauthenticated remote attacker could exploit this by sending specially crafted requests, leading to 100% CPU usage and a total denial of service that requires a server restart to resolve. | ||||
| CVE-2026-93569 | 2 Io.netty, Redhat | 23 Netty-codec-http, Amq Broker, Apache Camel Quarkus and 20 more | 2026-11-06 | 8.2 High |
| A flaw was found in Netty. A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prioritizes the Host header for the HTTP/2 :authority field, discarding the original request-target authority. This inconsistency can allow an attacker to bypass security controls in Netty-based proxies or gateways, potentially leading to unauthorized access, cache poisoning, or misrouting of requests. | ||||
| CVE-2026-93568 | 2 Io.netty, Redhat | 24 Netty-codec-http, Amq Broker, Apache Camel Quarkus and 21 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/2 or HTTP/3 Extended CONNECT requests. Netty's HTTP-object conversion path incorrectly processes these requests as regular HTTP/1.1 CONNECT requests, leading to a loss of critical protocol and path information. This misinterpretation can allow attackers to bypass security policies, such as routing or authorization logic, in applications that rely on Netty for HTTP/2 or HTTP/3 communication, resulting in integrity loss. | ||||
| CVE-2026-93567 | 2 Io.netty, Redhat | 24 Netty-codec-http2, Amq Broker, Apache Camel Quarkus and 21 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty's HTTP/2 codec. When converting HTTP/1 CONNECT requests to HTTP/2, the component incorrectly uses the Host header instead of the CONNECT authority-form request-target for the tunnel authority. A remote attacker can exploit this by supplying a different Host header, leading to a malformed HTTP/2 CONNECT request. This can bypass security controls such as tunnel allow-lists or egress policies, resulting in integrity loss. | ||||
| CVE-2026-93565 | 2 Red Hat, Redhat | 23 Red Hat Amq Broker 7, Amq Broker, Amq Clients and 20 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty RtspDecoder. The `RtspMethods.valueOf()` function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol (RTSP) requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. This vulnerability allows an attacker to bypass method-based access controls and can also be used to launder malicious requests through Netty-based RTSP proxies, making them appear legitimate to backend systems. | ||||
| CVE-2026-93564 | 1 Redhat | 20 Amq Broker, Amq Broker 7, Apache Camel Quarkus and 17 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service (DoS) for the affected system. | ||||
| CVE-2026-93558 | 2 Io.netty, Redhat | 24 Netty-codec-http, Amq Broker, Amq Broker 7 and 21 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive memory. Eventually, this can cause the Java Virtual Machine (JVM) to exhaust its heap, resulting in a Denial of Service (DoS) for the affected server. | ||||
| CVE-2026-93491 | 2 Io.netty, Redhat | 23 Netty-codec-http, Amq Broker, Amq Broker 7 and 20 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty's HttpServerCodec. A remote, unauthenticated attacker can exploit this vulnerability by pipelining HTTP/1.1 requests on a single connection and withholding reads. This action causes the methodOverflowQueue to grow without limit, leading to unbounded heap memory consumption and a denial of service due to memory exhaustion. | ||||
| CVE-2026-93488 | 2 Io.netty, Redhat | 23 Netty-codec-http, Amq Broker, Amq Clients and 20 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAX_VALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYN_STREAM frames with FLAG_FIN=0, causing unbounded heap and direct memory allocation that can lead to JVM OutOfMemoryError and a denial of service. | ||||
| CVE-2026-92855 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.4 High |
| A flaw was found in the SAML identity broker component of Keycloak, which is used to delegate authentication to external identity providers. The issue occurs because the broker fails to verify that a user actually possesses the private key associated with a holder-of-key assertion. An attacker who intercepts a victim signed assertion can replay it to gain unauthorized access and impersonate the victim without needing their private key. | ||||
| CVE-2026-0047 | 1 Google | 1 Android | 2026-11-06 | 8.4 High |
| In dumpBitmapsProto of ActivityManagerService.java, there is a possible way for an app to access private information due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. | ||||
| CVE-2026-114545 | 1 Drupal | 1 Fullcalendar View | 2026-11-06 | 5.4 Medium |
| Incorrect Authorization vulnerability in Drupal Fullcalendar View allows Forceful Browsing. This issue affects Fullcalendar View versions: from 0.0.0 to 5.2.6. | ||||
| CVE-2026-78190 | 1 Perl | 1 Webdyne | 2026-11-06 | 6.1 Medium |
| WebDyne versions from 2.014 before 3.022 for Perl reflect request parameters unescaped into form field values, allowing cross-site scripting. The textfield, password_field and filefield tags fill their value attribute from the request parameter of the same name. WEBDYNE_CGI_AUTOESCAPE, which controls escaping of these values, defaults to off. From 2.022, WebDyne::HTML::Tiny also replaced its entity_encode method with one that returns its input unchanged, so enabling WEBDYNE_CGI_AUTOESCAPE has no effect. A remote attacker can inject script into any page using these tags through a crafted link. | ||||
| CVE-2026-118394 | 1 Gitea | 1 Gitea | 2026-11-06 | 4.3 Medium |
| The OAuth2 userinfo endpoint (`/login/oauth/userinfo`) decided whether to limit the `groups` claim to public organizations by re-parsing the `Authorization` header as an OAuth2 access token instead of using the scope of the credential that authenticated the request. When a public-only OAuth2 token was sent as a query parameter or form field, or a public-only personal access token was used, that scope came back empty and the claim listed the token owner's private organizations, teams and concealed memberships. The disclosure is limited to the owner's organization and team names and memberships; no repository content is exposed. The endpoint now uses the scope of the authenticating token. | ||||
| CVE-2026-74760 | 1 Perl | 1 Google::auth | 2026-11-06 | 8.8 High |
| Google::Auth versions from 0.11 through 0.12 for Perl accept an authorization code from any local process because the gcloud-auth login callback does not check the OAuth state. The gcloud-auth login and application-default login commands send a state parameter with the authorization request, then take the code from the first request to reach their loopback listener without comparing the returned state. A local attacker can submit an authorization code for their own Google account. The CLI exchanges it and stores the refresh token as the user's credentials, so the user's tools then act as the attacker's account. | ||||
| CVE-2026-90964 | 2026-11-06 | 5.3 Medium | ||
| The Essential Real Estate WordPress plugin before 5.3.5 does not restrict the recipient of one of its contact email actions, allowing unauthenticated users to send emails to arbitrary addresses with an attacker-controlled sender header and message body through the site. | ||||
| CVE-2026-90965 | 2026-11-06 | 5.3 Medium | ||
| The Essential Real Estate WordPress plugin before 5.3.5 does not perform a publication-status or authorization check in two of its AJAX actions, allowing unauthenticated users to retrieve the images attached to property listings that have not been published. | ||||
| CVE-2026-90966 | 2026-11-06 | 4.3 Medium | ||
| The Essential Real Estate WordPress plugin before 5.3.5 does not verify, in one of its AJAX actions, that a listing package selected for free activation is genuinely free or that the requesting user is entitled to it, allowing a self-registered customer to activate a paid package without payment and cause the site to record a paid invoice at the package's full price. | ||||
