A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...
libkcapi: Infinite loop denial of service in libkcapi _kcapi_aio_read_all() due to unhandled io_getevents() timeout return
A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output AIO interface. By reusing an AIO-enabled handle after a prior completion error, the kcapiaioreadall function can enter a non-terminating wait loop. This can lead to a persistent...
libkcapi: Memory corruption via uncanceled AIO requests on error in libkcapi's one-shot AIO path
Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers...
undici: undici: Denial of Service via unbounded WebSocket PONG buffering
A flaw was found in undici. A malicious or compromised WebSocket server can trigger a Denial of Service DoS by repeatedly sending small PING messages while refusing to read the client's automated replies. Because the client ignores flow-control signals when writing responses to the network socket...
undici: undici: Denial of Service via memory exhaustion in EventSource client
A flaw was found in undici. A malicious server can trigger a Denial of Service DoS by exhausting application memory. When an application connects to an untrusted Server-Sent Events SSE feed, the EventSource parser does not properly limit retained internal state when processing fragmented lines or...
undici: undici: Denial of Service via TLS renegotiation with mismatched certificate
A flaw was found in undici. A remote server can cause a Denial of Service DoS by initiating a Transport Layer Security TLS renegotiation and presenting a certificate with a mismatched hostname. Because the client application fails to properly handle the resulting verification error, an uncaught...

An update for Red Hat Hardened Images RPMs is now available. This update includes the following RPMs: nodejs26: nodejs26-26.12.1-0.1.hum1 aarch64, s390x, x8664 nodejs26-bin-26.12.1-0.1.hum1 noarch nodejs26-devel-26.12.1-0.1.hum1 aarch64, s390x, x8664 nodejs26-docs-26.12.1-0.1.hum1 noarch...
nodejs: nodejs: TLS certificate hostname bypass via fullwidth-digit IP hostnames
A flaw was found in the Node.js TLS stack. Improper normalization of hostnames that use fullwidth Unicode digits to represent an IPv4 address can cause certificate hostname verification to accept a certificate that does not identify the intended peer. This may allow an attacker who can influence...
nodejs: nodejs: dns.resolve truncates hostnames containing a NUL character
A flaw was found in the Node.js DNS resolver APIs. Hostnames passed to dns.resolve that contain an embedded NUL character can be truncated when processed by c-ares. An attacker who can supply such a name may cause the application to resolve and act on an unintended hostname...
undici: undici: Certificate validation bypass via dropped TLS options in Agent
A flaw was found in undici. This vulnerability may allow a remote attacker to intercept or modify encrypted communications by bypassing custom certificate validation. The issue occurs because the Agent dispatcher discards caller-supplied Transport Layer Security TLS verification functions during...
undici: undici: Denial of Service via unhandled stream error on excessive content encodings
A flaw was found in undici. When an application sends a request to a malicious remote server, the server can return a response with excessive content encodings and immediately close the connection. Because the underlying response stream is left unhandled, this abrupt closure triggers an unhandled...

brotli: Out-of-Bounds Write in Google Brotli Decoder
A flaw was found in the Google Brotli decoder. An out-of-bounds write in the block-type switch handling in c/dec/decode.c can be triggered by a crafted Brotli-compressed stream. When an application decompresses untrusted Brotli data, this can lead to memory disclosure, denial of service, or...
php: fatal error handling retains stale request state leading to use-after-free
A flaw was found in PHP's error handling and worker process state management. PHP contains error handling, object, and extension state that is retained by the process but points to memory owned by a single request. A fatal error can interrupt an operation or cleanup phase before that state is...
