CVE-2026-75805 NULL Pointer Dereference in CMP Client Revocation Response Handling

Issue summary: A CMP client that requests certificate revocation on the basis of a PKCS10 CSR may dereference a NULL pointer and terminate abnormally when processing a crafted revocation response. Impact summary: The NULL pointer dereference happens on a read which leads to a crash and a Denial o...

CVE-2026-75804

The OpenSSL QUIC stack fails to enforce connection-level flow control for streams, a vulnerability categorized as CWE-770 . While the stack validates stream-level limits, it neglects connection-level limits, allowing a remote peer to send more bytes than permitted by the connection window as long...

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-2026-72897 Out-of-Bounds Access After SSL_set_SSL_CTX() During a Handshake

Issue summary: A TLS server that calls SSLsetSSLCTX to switch a connection to a different SSLCTX part way through a handshake may access memory beyond the end of an internal array if the replacement context knows about more provider signature algorithms than the context the connection was created...

CVE-2026-72897 Out-of-Bounds Access After SSL_set_SSL_CTX() During a Handshake

CVE-2026-72897

A flaw in OpenSSL allows a TLS server to perform an out-of-bounds read or fixed-value out-of-bounds write on the heap when using SSL_set_SSL_CTX() to switch contexts during a handshake. The root cause is that the internal array count for certificate validity flags is not refreshed when the connec...

CVE-2026-54875 Non-Constant-Time SM2 Scalar Multiplication on ARM64 and RISC-V

Issue summary: A non-constant-time optimized implementation of scalar point multiplication is used for SM2 private key operations on ARM64 and RISC-V platforms. Impact summary: An attacker able to measure the time taken by, or to observe the cache-line access pattern of SM2 signing or decryption ...

CVE-2026-97688 urllib3: Chunked Deflate streaming can enter an infinite loop

urllib3 is an HTTP client library for Python. From 2.6.2 until 2.8.0, HTTPResponse.stream and HTTPResponse.readchunked can enter an infinite loop because the Deflate decoder retains trailing bytes as unconsumed input after reaching end-of-stream and repeatedly decodes them without progress. The...

CVE-2026-97688

The Python HTTP client library urllib3 versions 2.6.2 through 2.8.0 are vulnerable to an infinite loop during chunked Deflate streaming. The issue exists because the Deflate decoder retains trailing bytes as unconsumed input after reaching the end-of-stream, repeatedly decoding them without progr...
