CVE-2026-71227 2 Redhat, Smuellerdd 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more 2026-09-21 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.

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 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more 2026-09-21 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-2026-87876 2 Openprinting, Redhat 6 Cups, Enterprise Linux, Hardened Images and 3 more 2026-09-21 3 Low
Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.
CVE-2026-85013 1 Redhat 2 Enterprise Linux, Hummingbird 2026-09-21 7.3 High
A flaw was found in environment-modules. A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability.
CVE-2026-43961 2 Redhat, Vim 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-09-21 7.8 High
A flaw was found in Vim's netrw plugin. A crafted filename containing quote characters and expression fragments can break out of the quoted context during mark/unmark operations, allowing arbitrary Vimscript execution. This can be leveraged to run shell commands with the privileges of the user running Vim.
CVE-2026-81627 2 Qemu, Redhat 8 Qemu, Enterprise Linux, Enterprise Linux For Nvidia 26 and 5 more 2026-09-21 8.2 High
A flaw was found in QEMU. The VAPIC setup hypercall in hw/i386/vapic.c does not validate that the writable RAM alias remains within the option ROM window. A privileged guest user on a Q35/KVM machine can position this alias over locked SMRAM, bypassing chipset D_LCK protection and injecting code into System Management Mode memory.
CVE-2026-54231 2 Fedoraproject, Redhat 7 Fedora, Automatic Bug Reporting Tool, Enterprise Linux and 4 more 2026-09-21 5.5 Medium
A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files.
CVE-2025-11234 1 Redhat 7 Enterprise Linux, Openshift, Rhel Aus and 4 more 2026-09-21 7.5 High
A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication.
CVE-2024-8176 1 Redhat 9 Devworkspace, Discovery, Enterprise Linux and 6 more 2026-09-21 7.5 High
A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage.
CVE-2026-54230 2 Fedoraproject, Redhat 8 Fedora, Automatic Bug Reporting Tool, Enterprise Linux and 5 more 2026-09-21 7 High
A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system.
CVE-2026-16445 1 Redhat 7 Enterprise Linux, Hummingbird, Openshift and 4 more 2026-09-21 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 options, such as a malicious root-path, next-server, or bootfile name, to a system using dracut's NetworkManager-based initrd network module. These options are improperly handled and written into a temporary shell script without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs during system boot.
CVE-2026-92747 1 Redhat 1 Enterprise Linux 2026-09-18 5 Medium
A flaw was found in `cockpit-machines`. This vulnerability allows a local attacker with the ability to inspect running processes to expose sensitive guest virtual machine (VM) credentials, such as `rootPassword` and `userPassword`. This occurs when the `install_machine.py` script passes these credentials as a JSON command-line argument during VM creation or installation. The exposure is limited to the period when the installation workflow is active and depends on host process-visibility policies.
