CVE-2026-32282

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...

RLSA-2026:5941 Important: golang security update

The golang packages provide the Go programming language compiler. Security Fixes: cmd/go: cmd/go: Arbitrary file write via malicious pkg-config directive CVE-2025-61731 net/url: Incorrect parsing of IPv6 host literals in net/url CVE-2026-25679 For more details about the security issues, including...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

golang: crypto/x509: excluded subdomain constraint does not restrict wildcard SANs

A flaw was found in the crypto/x509 package in the Go standard library. This vulnerability allows a certificate validation bypass via an excluded subdomain constraint in a certificated chain as it does not restrict the usage of wildcard SANs in the leaf certificate...

html/template: golang: html/template: Cross-Site Scripting (XSS) via improper context and brace depth tracking in JS template literals

A flaw was found in the html/template package. This vulnerability arises from improper tracking of context and brace depth within JavaScript JS template literals. A remote attacker could exploit these issues to cause content to be incorrectly or improperly escaped, leading to Cross-Site Scripting...

encoding/pem: Quadratic complexity when parsing some invalid inputs in encoding/pem

A potential denial of service flaw has been discovered in the golang encoding/pem module. Due to the design of the PEM parsing function, the processing time for some inputs scales non-linearly with respect to the size of the input. This affects programs which parse untrusted PEM inputs and may...

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,...

crypto/x509: Quadratic complexity when checking name constraints in crypto/x509

A potential denial of service flaw has been discovered in golang's crypto/x509 module. Due to the design of the name constraint checking algorithm, the processing time of some inputs scales non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary...

golang.org/x/net/http2: golang.org/x/net/http2: Denial of Service due to malformed HTTP/2 frames

A flaw was found in golang.org/x/net/http2. A remote attacker can exploit this vulnerability by sending specially crafted HTTP/2 frames, which are data packets used in the HTTP/2 protocol. Due to a missing check for null values, processing these specific frames types 0x0a through 0x0f can cause t...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

RockyLinux 10 : golang (RLSA-2026:5941)

The remote RockyLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:5941 advisory. cmd/go: cmd/go: Arbitrary file write via malicious pkg-config directive CVE-2025-61731 net/url: Incorrect parsing of IPv6 host literals in net/url...

CVE-2026-27143

A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially...
