CVE-2023-3576 3 Fedoraproject, Libtiff, Redhat 3 Fedora, Libtiff, Enterprise Linux 2026-01-22 5.5 Medium
A memory leak flaw was found in Libtiff's tiffcrop utility. This issue occurs when tiffcrop operates on a TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes this memory leak issue, resulting an application crash, eventually leading to a denial of service.
CVE-2025-7425 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-01-22 7.8 High
A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.
CVE-2025-6020 1 Redhat 16 Cert Manager, Confidential Compute Attestation, Discovery and 13 more 2026-01-22 7.8 High
A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions.

A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition.
CVE-2025-49796 1 Redhat 15 Cert Manager, Discovery, Enterprise Linux and 12 more 2026-01-22 9.1 Critical
A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory.
CVE-2025-49794 1 Redhat 14 Cert Manager, Enterprise Linux, Insights Proxy and 11 more 2026-01-22 9.1 Critical
A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.
CVE-2023-1393 3 Fedoraproject, Redhat, X.org 7 Fedora, Enterprise Linux, Rhel Aus and 4 more 2026-01-22 7.8 High
A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.
CVE-2025-32990 2 Gnu, Redhat 9 Gnutls, Ceph Storage, Discovery and 6 more 2026-01-22 6.5 Medium
A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.
CVE-2025-32988 2 Gnu, Redhat 9 Gnutls, Ceph Storage, Discovery and 6 more 2026-01-22 6.5 Medium
A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior.
CVE-2025-8114 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Openshift 2026-01-22 4.7 Medium
A flaw was found in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange (KEX) process, an allocation failure in cryptographic functions may lead to a NULL pointer dereference. This issue can cause the client or server to crash.
CVE-2025-7519 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-01-22 6.7 Medium
A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy file properly.
CVE-2025-6395 1 Redhat 7 Ceph Storage, Discovery, Enterprise Linux and 4 more 2026-01-22 6.5 Medium
A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite().
CVE-2023-47038 3 Fedoraproject, Perl, Redhat 5 Fedora, Perl, Enterprise Linux and 2 more 2026-01-22 7 High
A vulnerability was found in perl 5.30.0 through 5.38.0. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
CVE-2025-0306 1 Redhat 2 Enterprise Linux, Storage 2026-01-22 7.4 High
A vulnerability was found in Ruby. The Ruby interpreter is vulnerable to the Marvin Attack. This attack allows the attacker to decrypt previously encrypted messages or forge signatures by exchanging a large number of messages with the vulnerable service.
CVE-2024-28835 1 Redhat 2 Enterprise Linux, Rhel Eus 2026-01-22 5 Medium
A flaw has been discovered in GnuTLS where an application crash can be induced when attempting to verify a specially crafted .pem bundle using the "certtool --verify-chain" command.
CVE-2025-57850 1 Redhat 1 Openshift Devspaces 2026-01-22 5.2 Medium
A container privilege escalation flaw was found in certain CodeReady Workspaces images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.
CVE-2025-12548 1 Redhat 1 Openshift Devspaces 2026-01-22 9 Critical
A flaw was found in Eclipse Che che-machine-exec. This vulnerability allows unauthenticated remote arbitrary command execution and secret exfiltration (SSH keys, tokens, etc.) from other users' Developer Workspace containers, via an unauthenticated JSON-RPC / websocket API exposed on TCP port 3333.
CVE-2025-9566 1 Redhat 7 Enterprise Linux, Openshift, Openshift Devspaces and 4 more 2026-01-22 8.1 High
There's a vulnerability in podman where an attacker may use the kube play command to overwrite host files when the kube file container a Secrete or a ConfigMap volume mount and such volume contains a symbolic link to a host file path. In a successful attack, the attacker can only control the target file to be overwritten but not the content to be written into the file. Binary-Affected: podman Upstream-version-introduced: v4.0.0 Upstream-version-fixed: v5.6.1
CVE-2025-21605 4 Debian, Lfprojects, Redhat and 1 more 9 Debian Linux, Valkey, Discovery and 6 more 2026-01-21 7.5 High
Redis is an open source, in-memory database that persists on disk. In versions starting at 2.6 and prior to 7.4.3, An unauthenticated client can cause unlimited growth of output buffers, until the server runs out of memory or is killed. By default, the Redis configuration does not limit the output buffer of normal clients (see client-output-buffer-limit). Therefore, the output buffer can grow unlimitedly over time. As a result, the service is exhausted and the memory is unavailable. When password authentication is enabled on the Redis server, but no password is provided, the client can still cause the output buffer to grow from "NOAUTH" responses until the system will run out of memory. This issue has been patched in version 7.4.3. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways. Either using network access control tools like firewalls, iptables, security groups, etc, or enabling TLS and requiring users to authenticate using client side certificates.
CVE-2022-49465 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-01-21 7.8 High
In the Linux kernel, the following vulnerability has been resolved: blk-throttle: Set BIO_THROTTLED when bio has been throttled 1.In current process, all bio will set the BIO_THROTTLED flag after __blk_throtl_bio(). 2.If bio needs to be throttled, it will start the timer and stop submit bio directly. Bio will submit in blk_throtl_dispatch_work_fn() when the timer expires.But in the current process, if bio is throttled. The BIO_THROTTLED will be set to bio after timer start. If the bio has been completed, it may cause use-after-free blow.
