| CVE-2026-72693 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-09-15 | 7.8 High |
| `openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat("/proc/<pid>/fd/0")`. `stat()` on `/proc/<pid>/fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path. | ||||
| CVE-2026-58015 | 2 Gnome, Redhat | 15 Glib, Cert Manager, Discovery and 12 more | 2026-09-15 | 5.9 Medium |
| A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash. | ||||
| CVE-2026-58014 | 2 Gnome, Redhat | 15 Glib, Cert Manager, Discovery and 12 more | 2026-09-15 | 7.3 High |
| A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary. | ||||
| CVE-2026-15816 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 7 more | 2026-09-15 | 7.5 High |
| A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling. | ||||
| CVE-2026-11332 | 1 Redhat | 20 Acm, Ansible Automation Platform, Ansible Automation Platform Developer and 17 more | 2026-09-14 | 7.8 High |
| A flaw was found in ansible-core. The ansible-galaxy role install command processes dependency specifications from a role's meta/requirements.yml file. Due to improper neutralization of argument delimiters, a malicious role author can inject arbitrary git configuration flags through the src field. This allows arbitrary code execution on the machine of a user who installs the role via ansible-galaxy role install. | ||||
| CVE-2026-90996 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-09-14 | 4 Medium |
| A flaw was found in sssd. A local unprivileged user could send a specially crafted request with a zero-length body to the Network Security Services (NSS) responder. This could lead to a denial-of-service condition, causing the NSS responder to become unstable or terminate. This vulnerability affects the availability of the system responder. | ||||
| CVE-2026-90994 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-09-14 | 4 Medium |
| A flaw was found in sssd, specifically within the PAM (Pluggable Authentication Modules) responder's protocol v1 parser, pam_parse_in_data(). A local client with access to the PAM responder's UNIX socket can exploit this by negotiating protocol v1 and sending an empty or truncated PAM request body. This can trigger an out-of-bounds read, potentially causing the PAM responder to terminate or restart, leading to a local denial of service. | ||||
| CVE-2026-90463 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-09-14 | 4 Medium |
| A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure. | ||||
| CVE-2026-90995 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-09-14 | 5.5 Medium |
| A flaw was found in SSSD (System Security Services Daemon). A local attacker with privileges to connect to the PAM (Pluggable Authentication Modules) responder socket can send a specially crafted protocol request. If the `pam_app_services` configuration is enabled and the service item is omitted from the request, a NULL pointer dereference can occur. This vulnerability leads to a denial of service, causing the PAM responder to crash and disrupt authentication services. | ||||
| CVE-2026-14164 | 3 Libarchive, Red Hat, Redhat | 12 Libarchive, Enterprise Linux, Discovery and 9 more | 2026-09-14 | 7.5 High |
| A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service. | ||||
| CVE-2026-3833 | 2 Gnu, Redhat | 15 Gnutls, Discovery, Enterprise Linux and 12 more | 2026-09-14 | 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-2026-42010 | 2 Gnu, Redhat | 15 Gnutls, Ai Inference Server, Discovery and 12 more | 2026-09-14 | 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-2026-6893 | 1 Redhat | 11 Dracut, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-09-14 | 7.5 High |
| A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior. | ||||
| CVE-2026-2340 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-09-14 | 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-2026-3012 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-09-14 | 8 High |
| A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications. | ||||
| CVE-2026-71227 | 2 Redhat, Smuellerdd | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-09-14 | 5.1 Medium |
| A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive. | ||||
| CVE-2026-71226 | 2 Redhat, Smuellerdd | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-09-14 | 7.3 High |
| Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers. | ||||
| CVE-2026-71225 | 2 Redhat, Smuellerdd | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-09-14 | 6.5 Medium |
| A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs (over 64 KiB) in stateful modes such as Counter (CTR) or Cipher Block Chaining (CBC), the library improperly reuses the Initialization Vector (IV) for each internal data chunk. A remote attacker could potentially exploit this by making an application that uses libkcapi process specially crafted large inputs. This can lead to a significant weakening of data confidentiality, as the repeated IV use can expose relationships in encrypted plaintext, and may also affect data integrity by causing incorrect cryptographic processing. | ||||
| CVE-2026-16313 | 1 Redhat | 9 Enterprise Linux, Openshift, Openshift Container Platform and 6 more | 2026-09-14 | 7.6 High |
| A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected. | ||||
| CVE-2026-84828 | 1 Redhat | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-09-13 | 6.5 Medium |
| A flaw was found in PCS (Pacemaker Configuration System). A local attacker with membership in the 'haclient' group can exploit the 'pcs host auth --token' command to read the contents of arbitrary files on the filesystem, provided the files are shorter than 256 bytes. The file contents are read with root privileges by the pcsd daemon and can be exfiltrated by the attacker through subsequent cluster node communication. This allows disclosure of sensitive data such as API keys, tokens, or configuration secrets that would otherwise be inaccessible to the attacker. | ||||
