score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
All OpenShift Container Platform 4.14 users are advised to upgrade to these
updated packages and images when they are available in the appropriate
release channel. To check for available updates, use the OpenShift CLI (oc)
or web console. Instructions for upgrading a cluster are available at
https://docs.redhat.com/en/documentation/openshift_container_platform/4.14/html-single/updating_clusters/index#updating-cluster-cli.

A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.

Threats
Impact
Important
A flaw was found in the Stream Control Transmission Protocol (SCTP) implementation within the Linux kernel. A remote attacker could send a specially crafted sequence of ASCONF (Add IP Address Configuration) chunks, including DEL-IP (Delete IP Address) parameters, to trigger a use-after-free condition. This memory corruption could lead to a system crash, resulting in a denial of service, and potentially allow for arbitrary code execution.
7.8 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-43114
Threats
Impact
Important
A flaw was found in PCRE2. An out-of-bounds write vulnerability exists in the `pcre2_dfa_match` function due to improper size checking when reusing cached workspace blocks. A remote attacker could exploit this by providing a specially crafted regular expression or a recursive pattern in conjunction with a small heap limit. This could lead to data corruption or potentially arbitrary code execution, compromising the integrity and availability of the system.
8.2 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-43114
Threats
Impact
Important
A flaw was found in PCRE2, a library for processing regular expressions. The `pcre2_jit_match` function, which handles just-in-time (JIT) compilation for regular expressions, incorrectly manages memory when processing certain inputs. This memory corruption vulnerability could allow a local attacker to cause the application to crash, leading to a denial of service, or potentially execute unauthorized code.
7.4 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-43114
Threats
Impact
Important
A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during packet handling, potentially leading to arbitrary code execution on the host, a system crash resulting in Denial of Service (DoS), or information disclosure of sensitive memory.
8.8 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-43114
Threats
Impact
Important
A flaw was found in pcre2. When an application processes attacker-controlled regular expressions using certain Just-In-Time (JIT) compiler interfaces, an out-of-bounds write with arbitrary data can occur. An attacker could exploit this vulnerability to achieve arbitrary code execution, corrupt memory, or cause a denial of service (DoS).
7.6 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-43114
Threats
Impact
Important
The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.

"text": "This IMPORTANT-severity flaw affects the Linux kernel as shipped in Red Hat products, including the kernel and kernel-rt packages in Red Hat Enterprise Linux and the kernels shipped in Red Hat In-Vehicle OS. The IPv4 networking subsystem does not validate packet checksum metadata before completing a checksum: when a packet with a malformed checksum_start value enters the IPv4 stack, skb_checksum_help() can write out of bounds and corrupt the network header and other kernel memory (CWE-787). A local attacker or an untrusted guest virtual machine able to transmit such packets into an affected host could exploit this to crash the system (denial of service), disclose sensitive kernel memory, or potentially execute arbitrary code on the host. Red Hat tracks this flaw as a KEV active-exploit case. All currently tracked Red Hat product streams are marked affected, and fixes are being pursued by the responsible Red Hat product teams under delegated resolution. Red Hat\u0027s severity differs from the upstream assessment: Red Hat assigns a CVSS 3.1 score of 8.8 (IMPORTANT, AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), while the CVE.org record assigns 9.3 (CRITICAL, AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H); the two assessments differ on the privileges-required metric.",

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
