CVE-2026-94184 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 5.3 Medium
A stack-based buffer overflow flaw was found in fetchmail when built with NTLM support. A malicious or compromised mail server advertising NTLM authentication can send a crafted Type 2 challenge that causes fetchmail to write past a fixed stack buffer while building the NTLM authenticate response. This may lead to remote code execution depending on stack-frame layout, or to authentication failure or process termination under memory hardening.
CVE-2026-93683 1 Redhat 3 Enterprise Linux, Openshift, Openstack 2026-11-06 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-2026-93653 2 Poppler, Redhat 5 Poppler, Enterprise Linux, Hardened Images and 2 more 2026-11-06 5.5 Medium
A denial of service flaw was found in Poppler's Splash backend. A crafted PDF with tiling-pattern geometry approaching the int32 boundary can cause SplashOutputDev::tilingPatternFill to compute an attacker-controlled repeat count that drives an excessively long loop in the pattern-fill scanline routine, without a corresponding memory allocation. An attacker could exploit this by supplying a malicious PDF to an application that renders it via Poppler's Splash backend, causing the rendering process to consume 100% CPU for an attacker-controlled, extended duration.
CVE-2026-93433 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 5.5 Medium
A flaw was found in libstoragemgmt. An attacker with control over a local or virtual storage device could provide specially crafted SCSI (Small Computer System Interface) Vital Product Data (VPD) page 0x80 data. This malformed data, specifically an untrusted page length field, can lead to a stack buffer overflow in the `_sg_parse_vpd_80()` function during serial number parsing. Successful exploitation could result in a denial of service by crashing or destabilizing the process querying the serial number.
CVE-2026-93011 3 Dnsmasq, Red Hat, Redhat 9 Dnsmasq, Enterprise Linux, Ceph Storage and 6 more 2026-11-06 5.3 Medium
A flaw was found in dnsmasq. After a reduction of internal domain-name buffer sizes, the DNSSEC validator can write a few bytes past a name buffer when converting names to and from DNS wire format. An attacker who can cause the server to validate a crafted DNSSEC response may overwrite a small amount of adjacent heap metadata. DNSSEC support is not compiled in by default and must also be enabled at runtime.
CVE-2026-93007 3 Dnsmasq, Red Hat, Redhat 9 Dnsmasq, Enterprise Linux, Ceph Storage and 6 more 2026-11-06 5.3 Medium
A flaw was found in dnsmasq. The TCP DNS service uses a small fixed pool of child processes and does not set a receive timeout on client connections. A remote attacker can open idle TCP connections to port 53 and occupy the entire pool, preventing new TCP DNS connections and DNSSEC validation that requires TCP fallback. UDP DNS resolution continues, and occupied slots are released after a fixed lifetime.
CVE-2026-93006 3 Dnsmasq, Red Hat, Redhat 9 Dnsmasq, Enterprise Linux, Ceph Storage and 6 more 2026-11-06 6.8 Medium
A flaw was found in dnsmasq. The TFTP server can serve the wrong file contents because a recently used transfer cache is not invalidated when a transfer finishes. An attacker on the local network who can request a TFTP file may cause a later client to receive previously cached data instead of the requested file. In PXE network-boot environments this can substitute attacker-chosen boot content for a victim machine.
CVE-2026-92821 2 Redhat, Sssd 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more 2026-11-06 6.8 Medium
A flaw was found in SSSD. When configured to evaluate password expiration warnings before restrictive access rules in LDAP (Lightweight Directory Access Protocol) environments, an expired-password warning terminates rule evaluation early and treats the access request as successful. A remote authenticated user with an expired password using an alternative authentication method, such as SSH public key authentication, can exploit this flaw to bypass access control restrictions and gain unauthorized access to protected systems.
CVE-2026-92382 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 4.1 Medium
An out-of-bounds write flaw was found in usbredir. Starting an isochronous OUT stream with a transfer count of 1 leaves the stream's single transfer buffer permanently unsubmitted, defeating the bounds check in usbredirhost_iso_packet() and allowing a usbredir peer to write past the end of the packet descriptor array on every subsequent isochronous packet.
CVE-2026-92091 1 Redhat 5 Ansible Automation Platform, Enterprise Linux, Openshift Ai and 2 more 2026-11-06 5.9 Medium
A flaw was found in jwcrypto. The JWK.import_key() function validates the key_ops JWK member for duplicate values using an algorithm with O(n^2) time complexity, and the length of key_ops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large key_ops array to an application that passes attacker-controlled key material to a public key-import API (reachable via ECDH-ES key agreement, OIDC dynamic client registration, DPoP, or ACME account key registration, among others) to consume excessive CPU time, resulting in a denial of service.
CVE-2026-91786 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 6.1 Medium
A flaw was found in GNOME Shell. When processing icons from a remote search provider via D-Bus, the system fails to validate the icon's declared dimensions against the actual data buffer size. A malicious or compromised remote search provider could exploit this by providing oversized icon dimensions, leading to an out-of-bounds read. This can cause the GNOME Shell process to crash, disrupting the user's session, and potentially disclose sensitive information from adjacent memory.
CVE-2026-91920 1 Redhat 6 Camel Spring Boot, Enterprise Linux, Jboss Enterprise Application Platform and 3 more 2026-11-06 6.5 Medium
A flaw was found in the ChunkReader component of the Undertow web server, which is used to handle chunked transfer encoding in HTTP requests. The issue occurs because a security check for the chunk size is performed before the value is shifted, allowing a specifically crafted 15-digit chunk size to bypass the limit and overflow into internal state flags. This can cause the server to terminate a request body prematurely and interpret the remaining data as a separate, smuggled request.
CVE-2026-117614 2 Jenkins, Jenkins Project 2 Jenkins, Jenkins 2026-11-06 8.8 High
Jenkins 2.587 and earlier, LTS 2.580.1 and earlier converts the launch commands in older agent configurations into launchers provided by the Command Agent Launcher Plugin without checking whether they have been approved by an administrator, allowing attackers with Agent/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM.
CVE-2026-117619 2 Jenkins, Jenkins Project 2 Jenkins, Jenkins 2026-11-06 8.1 High
Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows requests authenticated using HTTP Basic authentication, including with an API token, to obtain a "remember me" cookie, allowing attackers who have obtained a user's API token to retain access to Jenkins using a "remember me" cookie after the API token is revoked or expires.
CVE-2026-117620 2 Jenkins, Jenkins Project 2 Jenkins, Jenkins 2026-11-06 8.8 High
Jenkins 2.587 and earlier, LTS 2.580.1 and earlier allows attackers with Overall/Read permission to trigger warnings in the "Manage Old Data" feature that can be acted on by administrators to inject attacker-controlled data, overriding existing user account information, including login passwords.
CVE-2026-63017 1 Subnet Solutions 3 Powersystem Center 2020, Powersystem Center 2024, Powersystem Center 2026 2026-11-06 9 Critical
Incorrect authorization in PowerSYSTEM Center allows a low-privileged, authenticated user to access resources normally limited to administrators.
CVE-2026-63774 1 Subnet Solutions 2 Powersystem Center 2024, Powersystem Center 2026 2026-11-06 9 Critical
Insufficient input validation in the PowerSYSTEM Center report designer allows an authenticated user to execute unauthorized SQL commands.
CVE-2026-91205 1 Redhat 1 Enterprise Linux 2026-11-06 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-2026-91203 1 Redhat 1 Enterprise Linux 2026-11-06 6 Medium
A flaw was found in cockpit-files. This vulnerability allows a local attacker to exploit a timing issue, known as a symlink race condition, during privileged file operations such as changing file ownership or permissions. By manipulating directory entries and winning this race, the attacker can redirect these operations to unintended files. This could lead to unauthorized changes in file ownership and permissions on arbitrary files, potentially compromising system integrity and availability by altering system or application states or rendering services unusable.
CVE-2026-91202 1 Redhat 1 Enterprise Linux 2026-11-06 6.1 Medium
A flaw was found in cockpit-files. A low-privileged local user can exploit this vulnerability by crafting a directory containing a symbolic link (symlink) and then using the privileged "Paste as owner" function. This allows for arbitrary file ownership changes outside the intended pasted directory, leading to a compromise of data integrity. In some cases, this could also lead to reduced confidentiality if the new ownership grants unauthorized read access. Exploitation requires user interaction to select a non-original owner during the paste operation.
