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-2026-89329 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-09-13 6.2 Medium
A flaw was found in `multipathd`. A local attacker with access to the `multipathd` UNIX control socket can exploit this vulnerability by sending valid commands and then ceasing to read replies. This action can cause the `multipathd` listener thread to block, leading to a Denial of Service (DoS) where legitimate Inter-Process Communication (IPC) operations may hang or time out. This issue does not result in privilege escalation, arbitrary code execution, or impact data confidentiality or integrity.
CVE-2026-87875 2 Openprinting, Redhat 6 Cups, Enterprise Linux, Hardened Images and 3 more 2026-09-11 4.3 Medium
The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.
CVE-2026-44495 2 Axios, Redhat 12 Axios, Advanced Cluster Management For Kubernetes, Advanced Cluster Security and 9 more 2026-09-11 7 High
Axios is a promise based HTTP client for the browser and Node.js. From 0.19.0 to before 0.31.1 and 1.15.2, Axios contains prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator. Axios does not itself create the prototype pollution. Exploitability requires a separate prototype-pollution vulnerability or equivalent attacker control over Object.prototype before Axios creates a request. This vulnerability is fixed in 0.31.1 and 1.15.2.
CVE-2026-87853 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-09-10 7.5 High
A flaw was found in SSSD's IdP authentication provider. The eval_access_token_buf() function compares the OIDC subject identifier using strncmp() with the authenticated user's identifier length, performing a prefix comparison instead of an exact match. An attacker whose IdP identifier is a strict prefix of a target user's identifier can authenticate as the target user.
CVE-2026-87876 2 Openprinting, Redhat 6 Cups, Enterprise Linux, Hardened Images and 3 more 2026-09-10 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-2026-18508 2 Gnu, Redhat 8 Tar, Discovery, Enterprise Linux and 5 more 2026-09-10 4.4 Medium
A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary and, when combined with a preexisting symbolic link under the working directory, may allow writing outside that boundary during a single extraction.
CVE-2026-18477 2 Gnu, Redhat 8 Tar, Discovery, Enterprise Linux and 5 more 2026-09-10 4.4 Medium
A TOCTOU (Time-of-Check Time-of-Use) vulnerability in GNU tar's incremental dumpdir 'X' rename handling allows a local attacker with write access to a directory being backed up to influence the restore process if the attacker has access to the system where the restore is being performed. During restoration, files or directories may be created, renamed or overwritten outside the intended extraction directory. This could lead to unauthorized file modification or, in some cases, privilege escalation. Exploitation does not require the attacker to modify or craft the archive, and standard backup and restore workflows—including extracting into a newly created directory without using the -P option do not mitigate the issue.
CVE-2026-16730 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-09-10 5.5 Medium
A flaw was found in dbus-broker. When the process file-descriptor limit is reached, EMFILE/ENFILE errors during peer setup (notably SO_PEERPIDFD) are handled as fatal failures, causing the broker to exit. A local attacker who can open many connections to the user session bus can trigger this and deny service to the desktop session. Flatpak applications can reach the host session bus through the dbus proxy.
CVE-2026-15588 1 Redhat 15 Cert Manager, Discovery, Enterprise Linux and 12 more 2026-09-10 5.3 Medium
A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.
CVE-2026-4897 2 Freedesktop, Redhat 5 Polkit, Enterprise Linux, Hummingbird and 2 more 2026-09-10 5.5 Medium
A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system.
