CVE-2026-97689 urllib3: HTTPResponse.stream()/read_chunked() buffers an unbounded chunk-size line into memory

urllib3 is an HTTP client library for Python. From 1.10.3 until 2.8.0, the HTTPResponse.readchunked and HTTPResponse.stream methods can allocate unbounded memory because the streaming chunk parser buffers the chunk-size field until newline or EOF without a length bound. The trigger is that a...

EUVD-2026-89015

Issue summary: A malicious remote peer may flood the local QUIC stack with NEWCONNECTIONID frames by avoiding a limit check on how many connection IDs the remote QUIC stack can use. Impact summary: The local QUIC stack sends a RETIRECONNID frame for every NEWCONNECTIONID frame it receives. The...

CVE-2026-84784 QUIC: Unbounded RETIRE_CONNECTION_ID Backlog

Issue summary: A malicious remote peer may flood the local QUIC stack with NEWCONNECTIONID frames by avoiding a limit check on how many connection IDs the remote QUIC stack can use. Impact summary: The local QUIC stack sends a RETIRECONNID frame for every NEWCONNECTIONID frame it receives. The...

CVE-2026-75804 QUIC Connection-Level Flow Control is Not Enforced for Streams

Issue summary: OpenSSL QUIC stack does not enforce connection level flow control for streams. Remote peers may send more bytes as long as they fit within the stream flow control limits. Impact summary: A malicious remote peer may exploit the lack of connection flow control for streams to make the...

CVE-2026-54873

A flaw in OpenSSL allows a remote attacker to cause a Denial of Service (DoS) by sending specially crafted network packets to a QUIC protocol endpoint. The vulnerability occurs because the QUIC stack retains memory in packet buffers until the receiving application copies the stream data, a design...

CVE-2026-54873 QUIC STREAM Fragment Metadata DoS

Issue summary: QUIC process may keep memory for QUIC packet buffer for much longer period than necessary. Impact summary: Remote peer can exploit this vulnerability by sending maliciously crafted packets, making the local QUIC stack to keep the memory for packet buffers allocated. The time for...

CVE-2026-35189 Excessive Memory Allocation in Relative CRLDP Processing

Issue summary: A certificate with many nameRelativeToCRLIssuer CRL distribution points causes disproportionate heap growth when OpenSSL caches X.509 extensions. Impact summary: Receiving a crafted certificate from a malicious peer can lead to significant memory pressure and possible Denial of...

RUSTSEC-2026-0317 A 512-byte workbook can provoke a multi-gigabyte allocation and abort the process

Affected versions passed caller-supplied bytes to calamine's Xlsx::new without first checking that they were a ZIP archive. Xlsx::new tests for password protection on its first line, which parses the input as an OLE/CFB container, and a sector-count field read from the file's own header reaches...

CVE-2026-54873: Allocation of Resources Without Limits or Throttling

Issue summary: QUIC process may keep memory for QUIC packet buffer for much longer period than necessary. Impact summary: Remote peer can exploit this vulnerability by sending maliciously crafted packets, making the local QUIC stack to keep the memory for packet buffers allocated. The time for...

CVE-2026-97507

A flaw was found in the Linux kernel's DM1105 media driver. A local user could cause a Denial of Service DoS through a kernel crash if Direct Memory Access DMA memory allocation fails during device initialization. Because the driver ignores the allocation return value, it proceeds to use a null...
