CVE-2026-72897

A flaw was found in openssl. When a server replaces its security context during an active Transport Layer Security TLS handshake, it fails to update the internal capacity tracking for cryptographic signature algorithms. A remote peer can exploit this issue by advertising specific signature...

CVE-2026-54873

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by sending specially crafted network packets to a QUIC protocol endpoint. Because the QUIC stack retains memory in packet buffers until the receiving application reads the stream data, an attacker can manipulate data...

CVE-2026-54872

A flaw was found in OpenSSL. A timing side-channel vulnerability in generic elliptic curve scalar multiplication allows an attacker to recover private cryptographic keys. When performing signature operations, such as the Elliptic Curve Digital Signature Algorithm ECDSA or SM2, using curves withou...

CVE-2026-42772

A flaw was found in OpenSSL. A remote attacker who establishes a QUIC network connection can cause a Denial of Service DoS by sending specially sequenced, out-of-order stream frames. Because the stream reassembly mechanism handles non-sequential data fragments inefficiently, processing these fram...

CVE-2026-75804

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS due to missing connection-level flow control enforcement in the QUIC protocol implementation. By opening multiple streams that respect individual stream limits while preventing data consumption, the attacker can forc...

Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack in the ARM64 and RISC-V optimized SM2 scalar multiplication, which selects conditional branches and table lookups by secret scalar bits. An attacker can learn the long term private key or a per signature nonce by measuring...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the X.509 extension cache, which computes the cache under a read lock and then installs the result under a write lock, so concurrent threads each install their own result and free the previous one while another thread...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the QUIC flow control enforcement, which applies the stream level window but not the connection level one. An attacker can force roughly 100 MB of allocation against a default 768 ...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference in the CMP client's handling of a revocation response, which compares the certificate named in the response against an issuer name and serial number that are unset when the revocation was requested by PKCS10 CSR...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the DTLS handshake retransmission handling, which reuses the existing buffer position when a retransmission timer fires during a write that paused mid-message, rather than resetting to the start of the message. An...

Improper Validation of Specified Quantity in Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input in the DTLS 1.2 record layer, which passes the record length to the cipher before checking that it covers the explicit IV and authentication tag, so an undersized record raises a fatal...

AZL-105585 CVE-2026-84784 affecting package openssl 3.3.7-6

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...

ALPINE-CVE-2026-84784

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...

AZL-105879 CVE-2026-84784 affecting package rust 1.96.1-2

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...

AZL-105567 CVE-2026-84782 affecting package openssl 3.3.7-6

Issue summary: The DTLS retransmission logic does not correctly handle a handshake message write that is suspended part-way through. The retransmitted message can be read past the message buffer and the retransmission overwrites the internal state the suspended write needs to resume correctly...

AZL-105363 CVE-2026-84782 affecting package openssl-fips-provider 3.1.2-2

Issue summary: The DTLS retransmission logic does not correctly handle a handshake message write that is suspended part-way through. The retransmitted message can be read past the message buffer and the retransmission overwrites the internal state the suspended write needs to resume correctly...

DEBIAN-CVE-2026-84784

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-2026-84783

Issue summary: The first concurrent use of the same X.509 certificate by several threads may cause its cached extension data to be freed while another thread is still using it. Impact summary: A remote, unauthenticated peer could crash a multi-threaded TLS client, or a multi-threaded TLS server...
