CVE-2026-107080

OpenJPEG 2.4.0 through 2.5.4, and git master through commit 8314119b, contains an out-of-bounds read and write in opjdwtencodeanddeinterleavev in src/lib/openjp2/dwt.c. This allows an attacker to cause a denial of service...

CVE-2026-93237

A flaw was found in the Linux kernel. An incorrect physical memory boundary check on LoongArch systems allows device memory allocations to fall outside the supported virtual memory mapping space. When the kernel attempts to map this out-of-bounds memory, an address wraparound occurs that silently...

CVE-2026-98894

A flaw was found in the AMD GPU driver within the Linux kernel. When handling overflow conditions in the Common Platform Error Record CPER ring buffer, the driver relies on parsed entry sizes from the buffer contents without verifying that the read pointer advances. Corrupt error record data can...

CVE-2026-98895

A flaw was found in the Linux kernel's mlx5 network driver. When destroying a hardware steering table configured with a default miss table, the driver fails to remove the entry from the associated miss table tracking list, leaving behind an invalid pointer. A local privileged user could exploit...

CVE-2026-93850

Mattermost versions 11.9.x = 11.9.1, 11.8.x = 11.8.5, 11.7.x = 11.7.10, 11.10.x = 11.10.1 fail to bind the volume of text extracted from an uploaded PDF which allows an authenticated user to exhaust server memory and cause a denial of service via a crafted PDF whose compressed content stream...

CVE-2026-116497

A NULL pointer dereference vulnerability was found in gssproxy. When a GSSXINITSECCONTEXT request is received with the targetname field absent, the daemon dereferences the resulting NULL pointer and crashes. The request requires no authentication, allowing any local user to crash the gssproxy...

encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

net/http: golang: golang: Denial of Service via crafted HTTP Range headers

A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...

net/textproto: mime/multipart: golang: golang: Denial of Service via memory limit bypass in multipart form parsing

A flaw was found in the mime/multipart and net/textproto packages in Go. A remote attacker could exploit this vulnerability by submitting a crafted multipart form request that bypasses configured memory limits when the remaining boundary limit is small. This issue allows the application to read a...

net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...

Important: Red Hat Security Advisory: RHOSO 18.0 os-diff security update

An update for golang-github-openstack-k8s-operators-os-diff is now available for Red Hat OpenStack Services on OpenShift 18.0 Antelope. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...

crypto/tls: golang: crypto/tls: Denial of Service via multiple ECH outer extension references

A flaw was found in crypto/tls. A remote attacker can trigger this vulnerability by sending a specially crafted packet containing multiple Encrypted Client Hello ECH outer extension references to a server. Processing these unauthorized references leads to excessive memory consumption, causing a...

crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

etcd: etcd: Denial of Service via unbounded TLS handshake goroutines

A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...
