CVE-2026-50257 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-07-27 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-2026-50256 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-07-27 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-2026-10517 1 Redhat 1 Quay 2026-07-27 5.8 Medium
Retracted following review by Red Hat Product Security and confirmation from the upstream Clair/Claircore maintainer. This CVE misattributes the described behavior to github.com/quay/claircore: the authentication mechanism in question (optional PSK, HTTP endpoint /indexer/api/v1/index_report) is implemented entirely in github.com/quay/clair; no PSK-related code exists anywhere in claircore's codebase or git history. The unauthenticated indexer API is Clair's documented, intentional design, authentication is an opt-in deployment choice, not a code defect. No fix commit was found in claircore between the version recorded as the affected boundary (1.5.52) and the following release (1.5.53); intervening commits are unrelated dependency and feature changes, so the "fixed in 1.5.52" status is inaccurate.
CVE-2026-64600 2 Linux, Redhat 8 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-07-24 7.8 High
In the Linux kernel, the following vulnerability has been resolved: xfs: resample the data fork mapping after cycling ILOCK xfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode, a data fork mapping, and a cow fork mapping. Unfortunately, these two helpers cycle the ILOCK to grab a transaction, which means that the mappings are stale as soon as we reacquire the ILOCK. Currently we refresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but we don't refresh the data fork mapping beforehand, which means that the xfs_bmap_trim_cow in that function queries the refcount btree about the wrong physical blocks and returns an inaccurate value in *shared. If *shared is now false, the directio write proceeds with a stale data fork mapping. Fix this by querying the data fork mapping if the sequence counter changes across the ILOCK cycle.
CVE-2026-53366 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Enterprise Linux Eus 2026-07-24 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ipv4: account for fraggap on the paged allocation path In __ip_append_data(), when the paged-allocation branch is taken, alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap, but the fraggap bytes carried over from the previous skb are copied into the new skb's linear area at offset transhdrlen by the subsequent skb_copy_and_csum_bits(). The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic.
CVE-2026-16743 1 Redhat 1 Enterprise Linux 2026-07-24 5.5 Medium
A flaw was found in accountsservice. The systemd-homed code path for SetIconFile opens a user-supplied filename as root without the validation and privilege drop performed by the classic handler. A local attacker with a systemd-homed-managed account can read arbitrary files accessible to the accounts-daemon process.
CVE-2026-56391 2 Gnu, Redhat 2 Coreutils, Hummingbird 2026-07-24 6.1 Medium
GNU coreutils uniq is vulnerable to an out‑of‑bounds read due to incorrect handling of multibyte input when the -w (--check-chars) option is used. The find_field() function miscalculates the byte length of characters by repeatedly processing a fixed pointer instead of advancing through the input, resulting in an inflated length value. This incorrect length is later used in a memcmp operation, causing reads beyond the allocated buffer when processing crafted multibyte input. When running GNU coreutils uniq with attacker-provided arguments, this behavior leads to a crash and potential adjacent heap memory exposure. This issue has been fixed in the commit d64e35a8a4c0e4608321433e0d84d917e4e36371.
CVE-2023-4875 3 Debian, Mutt, Redhat 3 Debian Linux, Mutt, Enterprise Linux 2026-07-24 2.2 Low
Null pointer dereference when composing from a specially crafted draft message in Mutt >1.5.2 <2.2.12
CVE-2023-4874 3 Debian, Mutt, Redhat 3 Debian Linux, Mutt, Enterprise Linux 2026-07-24 4.3 Medium
Null pointer dereference when viewing a specially crafted email in Mutt >1.5.2 <2.2.12
CVE-2026-64611 1 Redhat 1 Enterprise Linux 2026-07-23 7.5 High
A flaw was found in libcupsfilters. The cfIEEE1284NormalizeMakeModel() function enters an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field, causing sustained CPU consumption. A network-adjacent attacker could exploit this by broadcasting a specially crafted printer advertisement, leading to denial of service.
CVE-2026-16768 1 Redhat 1 Enterprise Linux 2026-07-23 5.3 Medium
A flaw was found in gdk-pixbuf. When parsing a specially crafted ICO file with pixel values that exceed the defined palette range, an out-of-bounds read can occur due to improper bounds checking against the actual palette size. This vulnerability causes heap bytes to be interpreted as valid palette indices and rendered as RGB pixel values in the output image, allowing an attacker to extract heap content via the generated output, such as a thumbnail.
CVE-2026-16745 2 Red Hat, Redhat 2 Red Hat Openshift Ai (rhoai), Openshift Ai 2026-07-23 8.8 High
A flaw was found in odh-dashboard, the web console component of Red Hat OpenShift AI (RHOAI). Due to incorrect network binding, a malicious actor within the cluster can bypass authentication and impersonate any user by providing an arbitrary access token. This allows an attacker to gain unauthorized access to the Kubernetes API, potentially leading to arbitrary code execution, privilege escalation, or information disclosure.
CVE-2026-15811 1 Redhat 2 Enterprise Linux, Openshift 2026-07-23 5.8 Medium
A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability.
CVE-2026-44190 1 Redhat 1 Ansible Automation Platform 2026-07-23 7.8 High
A flaw was found in the Ansible Lightspeed Visual Studio Code extension. This Command Injection vulnerability (CWE-78) allows a remote attacker to execute unauthorized commands on a user's system. The issue occurs because the `ansible.python.activationScript` setting, intended for a virtual environment activation script, does not properly validate user input as a file path. If a user opens or executes a specially crafted project, an attacker could exploit this to gain complete control over the user's system with the privileges of the Visual Studio Code application.
CVE-2025-10911 1 Redhat 11 Discovery, Enterprise Linux, Enterprise Linux Eus and 8 more 2026-07-23 5.5 Medium
A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash.
CVE-2026-11605 2 Isc, Redhat 3 Bind, Bind 9, Hummingbird 2026-07-23 7.5 High
The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to waste disproportionate CPU time. This issue affects BIND 9 versions 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, and 9.20.9-S1 through 9.20.24-S1.
CVE-2026-10649 2 Clusterlabs, Redhat 10 Pacemaker, Enterprise Linux, Enterprise Linux Eus and 7 more 2026-07-22 8.6 High
A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing.
CVE-2026-50659 2 Microsoft, Redhat 6 .net, .net Framework, Visual Studio 2022 and 3 more 2026-07-22 6.5 Medium
Improper encoding or escaping of output in .NET allows an authorized attacker to perform spoofing over a network.
CVE-2026-44191 1 Redhat 1 Ansible Automation Platform 2026-07-22 7.8 High
A flaw was found in the Visual Studio Code Ansible Lightspeed extension. This command injection vulnerability (CWE-78) arises from improper handling of the ansible.executionEnvironment.containerOptions and ansible.executionEnvironment.volumeMounts settings, allowing an attacker to inject shell separators. This can be triggered automatically during Language Server initialization or manually when executing a playbook. Successful exploitation leads to remote code execution (RCE) on the victim's machine with the privileges of the Visual Studio Code user, potentially resulting in a complete system compromise.
CVE-2026-16118 1 Redhat 1 Enterprise Linux 2026-07-22 7.1 High
A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption.
