CVE-2026-78408 2 Linux, Redhat 6 Util-linux, Enterprise Linux, Hardened Images and 3 more 2026-09-05 7.9 High
The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve(). Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an attacker-controlled target can inherit root's ability to move host processes between cgroups. After a privileged operator uses --join-cgroup against that target, an unprivileged user can migrate and terminate unrelated root processes.
CVE-2026-81665 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-09-04 7.5 High
A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.
CVE-2026-78410 2 Linux, Redhat 6 Util-linux, Enterprise Linux, Hardened Images and 3 more 2026-09-04 7.8 High
A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount(8) to bind another host directory. If the fstab entry also sets X-mount.owner, X-mount.group, or X-mount.mode, root then changes ownership or mode on that redirected inode.
CVE-2026-81666 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-09-04 6.5 Medium
An integer overflow was found in Corosync's handling of membership commit token messages. The length-validation check for these messages can be bypassed on 32-bit systems due to an integer overflow in the calculation of the expected message length, allowing a crafted network packet to trigger an out-of-bounds memory access that crashes the Corosync daemon. This results in a denial of service for the affected cluster node. The overflow does not occur on 64-bit systems, where the length calculation is correctly performed in 64-bit arithmetic.
CVE-2026-19582 2 Gnu, Redhat 5 Binutils, Enterprise Linux, Hardened Images and 2 more 2026-09-04 7.8 High
Red Hat Product Security has come to the conclusion that this CVE is false due to upstream security policy.
CVE-2026-49329 1 Redhat 2 Openshift, Openshift Container Platform 2026-09-03 7.5 High
A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users.
CVE-2026-78409 2 Linux, Redhat 6 Util-linux, Enterprise Linux, Hardened Images and 3 more 2026-09-03 7 High
The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to open_tree() with AT_SYMLINK_NOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with an fstab-authorized X-mount.subdir entry can attach a host path at the intended mountpoint.
CVE-2026-48864 2 Opensuse, Redhat 21 Libsolv, Discovery, Enterprise Linux and 18 more 2026-09-03 7.8 High
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2026-42013 2 Gnu, Redhat 15 Gnutls, Discovery, Enterprise Linux and 12 more 2026-09-03 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42011 1 Redhat 14 Discovery, Enterprise Linux, Enterprise Linux Eus and 11 more 2026-09-03 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
CVE-2026-14476 2 Redhat, Sssd 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-09-03 8 High
A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass.
CVE-2026-5260 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-09-03 8.2 High
A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure.
CVE-2026-3833 2 Gnu, Redhat 15 Gnutls, Discovery, Enterprise Linux and 12 more 2026-09-03 6.5 Medium
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-2340 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-09-03 6.5 Medium
A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.
CVE-2026-50237 1 Redhat 2 Openshift, Openshift Container Platform 2026-09-03 7.4 High
A Server-Side Request Forgery and supply chain flaw was found in the OpenShift Console Helm catalog proxy. A namespace tenant can plant a ProjectHelmChartRepository with an arbitrary URL that the console pod fetches server-side, bypassing tenant egress restrictions. Combined with catalog metadata poisoning and admin-mediated chart installation, this enables privilege escalation.
CVE-2026-50236 1 Redhat 2 Openshift, Openshift Container Platform 2026-09-03 7.4 High
An authenticated SSRF flaw was found in the OpenShift Console Dev Console webhook helpers. User-supplied target URLs are fetched server-side without validation, with path neutralization enabling arbitrary endpoint targeting and full response reflection from the console pod's privileged network position.
CVE-2026-49332 1 Redhat 2 Openshift, Openshift Container Platform 2026-09-03 8.5 High
A flaw was found in openshift/oauth-proxy. The proxy sets authenticated identity headers using only dash-variant keys (X-Forwarded-User) but does not strip underscore-variant keys (X_Forwarded_User) from incoming requests. WSGI and PHP frameworks normalize both variants to the same variable, allowing an authenticated low-privilege user to smuggle a forged identity that may override the legitimate authenticated identity in the upstream application.
CVE-2026-42010 2 Gnu, Redhat 15 Gnutls, Ai Inference Server, Discovery and 12 more 2026-09-03 7.1 High
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
CVE-2026-42009 2 Gnu, Redhat 26 Gnutls, Ai Inference Server, Discovery and 23 more 2026-09-03 7.5 High
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.
CVE-2026-33846 2 Gnu, Redhat 16 Gnutls, Ai Inference Server, Discovery and 13 more 2026-09-03 7.5 High
A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.
