CVE-2026-18651 2 Red Hat, Redhat 5 Enterprise Linux, 389 Directory Server, Directory Server and 2 more 2026-08-05 5.4 Medium
A flaw was found in 389 Directory Server. During SASL PLAIN authentication, the server installs connection-level bind credentials before performing the account-lock check. If the account is subsequently found to be locked, the bind is reported as failed to the client, but the already-installed authenticated state on the connection is not reverted. A client that supplies valid credentials for an account that has been administratively locked can continue to use the same connection with that account's privileges, defeating account lock as an access-revocation control.
CVE-2026-18739 2 Popt-devel, Redhat 4 Popt-static, Enterprise Linux, Hummingbird and 1 more 2026-08-05 2.5 Low
A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacker to execute arbitrary code if the host application then unsafely processes the altered data.
CVE-2026-50659 4 Apple, Linux, Microsoft and 1 more 22 Macos, Linux Kernel, .net and 19 more 2026-08-05 6.5 Medium
Improper encoding or escaping of output in .NET allows an authorized attacker to perform spoofing over a network.
CVE-2026-53704 2 Gstreamer Project, Redhat 4 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 1 more 2026-08-05 7.1 High
A flaw was found in GStreamer's RealMedia demuxer in the gst-plugins-ugly package. When processing a RealMedia file containing a specially crafted FILEINFO metadata section, the demuxer parses variable-name and variable-value pairs using re_skip_pascal_string() without validating that offsets remain within the mapped buffer. Additionally, the element count controlling the parsing loop is read from attacker-controlled data without validation, which can cause an infinite loop. A crafted RealMedia file can cause the application to crash, hang, or potentially read limited adjacent memory contents.
CVE-2026-53703 2 Gstreamer, Redhat 4 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 1 more 2026-08-05 7.1 High
A vulnerability was found in the GStreamer RealMedia demuxer (gst-plugins-ugly). When processing a RealMedia (.rm) file, the demuxer parses MDPR (media properties) chunks to configure audio streams. For audio stream header versions 4 and 5, the parser reads fields such as codec type, packet size, sample rate, channel count, and extra codec data length from fixed offsets within the chunk without first checking that the chunk contains enough data. If a malicious file provides an MDPR chunk that is too small to contain a complete audio stream header, the parser reads beyond the end of the buffer. This can cause the application to crash. In some cases, bytes read past the buffer boundary may be incorporated into stream metadata, which could result in limited information disclosure.
CVE-2025-5278 1 Redhat 7 Cost Management, Discovery, Enterprise Linux and 4 more 2026-08-05 4.4 Medium
A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data.
CVE-2026-50257 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50262 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 5.5 Medium
An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default.
CVE-2026-50258 2 Redhat, X.org 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more 2026-08-04 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50261 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50260 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in FreeCounter(). A client that sets up multiple SyncCounters and awaits on those triggers can trigger a use-after-free when destroying those counters via a second client connection. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50259 3 Redhat, X.org, Xorg 12 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 9 more 2026-08-04 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50263 2 Redhat, X.org 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more 2026-08-04 5.5 Medium
A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure.
CVE-2026-50256 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-11332 1 Redhat 14 Acm, Ansible Automation Platform, Ansible Automation Platform Developer and 11 more 2026-08-04 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-2026-14476 2 Redhat, Sssd 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-08-04 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-2025-5318 2 Libssh, Redhat 11 Libssh, Ai Inference Server, Enterprise Linux and 8 more 2026-08-04 5.4 Medium
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
CVE-2026-68743 2 Redhat, Sssd 3 Enterprise Linux, Openshift, Sssd 2026-08-04 5.5 Medium
A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
CVE-2023-4853 2 Quarkus, Redhat 21 Quarkus, Build Of Optaplanner, Build Of Quarkus and 18 more 2026-08-04 8.1 High
A flaw was found in Quarkus where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a denial of service.
CVE-2026-16526 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-08-04 8.8 High
A flaw in the PCP linux_sockets module exposes an unsecured internal connection. An attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.
