CVE-2026-64676

A flaw was found in Kata Containers. When the mem-agent feature is enabled, an untrusted host can bypass authorization checks in the kata-agent's memory management. This allows the host to tamper with in-guest memory, leading to attacker-controlled availability and performance degradation of...

AZL-105501 CVE-2026-84782 affecting package kata-containers 4.1.0.kata0-1

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-105522 CVE-2026-84784 affecting package kata-containers 4.1.0.kata0-1

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-105507 CVE-2026-75806 affecting package kata-containers 4.1.0.kata0-1

Issue summary: An established DTLS 1.2 association using an AEAD cipher suite can be terminated by a single unauthenticated datagram whose encrypted fragment is shorter than the mandatory explicit IV and authentication tag overhead. Impact summary: An attacker who can send a datagram that is rout...

AZL-105519 CVE-2026-77696 affecting package kata-containers 4.1.0.kata0-1

Issue summary: SM2 signature generation uses non-constant-time arithmetic on secret values, forming a timing side-channel. Impact summary: An attacker able to measure SM2 signing times may learn information about the per-signature secret nonce, which over many signatures can, via a lattice / Hidd...

AZL-105528 CVE-2026-75805 affecting package kata-containers 4.1.0.kata0-1

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...

AZL-105510 CVE-2026-75804 affecting package kata-containers 4.1.0.kata0-1

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...

AZL-105498 CVE-2026-72897 affecting package kata-containers 4.1.0.kata0-1

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...

AZL-105495 CVE-2026-54873 affecting package kata-containers 4.1.0.kata0-1

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...

AZL-105516 CVE-2026-54875 affecting package kata-containers 4.1.0.kata0-1

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 ...

AZL-105504 CVE-2026-54872 affecting package kata-containers 4.1.0.kata0-1

Issue summary: The generic elliptic-curve scalar multiplication used for ECDSA and SM2 signature operations with curves that do not have a dedicated implementation leaks information about the secret nonce through timing. Impact summary: An attacker able to measure signing times may learn...

AZL-105525 CVE-2026-42772 affecting package kata-containers 4.1.0.kata0-1

Issue summary: The QUIC stream reassembly algorithm performance deteriorates progressively as packets are arriving out of order. The worst case has a quadratic complexity proportional to the number of stream frames kept in the buffer for the received stream data. Impact summary: A remote QUIC pee...

AZL-105531 CVE-2026-35191 affecting package kata-containers 4.1.0.kata0-1

Issue summary: The OpenSSL QUIC server, when configured to not preform address validation, can be forced to count incoming packets multiple times in its unvalidated credit computation, leading to a violation of the RFC 9000 unvalidated connection amplification limit of 3 times the amount of data...

AZL-105513 CVE-2026-35189 affecting package kata-containers 4.1.0.kata0-1

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...

CVE-2026-100838

Contrast is a confidential-computing runtime for Kubernetes. In versions before 1.19.1, the Kata agent policies generated by the Contrast CLI contained a flaw in the CopyFile verification that allowed arbitrary writes to the guest root filesystem. A malicious process on the untrusted host able to...

CVE-2026-100833

Contrast edgelesssys/contrast versions 1.14.0 before 1.23.1 generate runtime policies that fail to detect all container image substitutions. A bad rebase during a Kata Containers update accidentally introduced an allowstorage rule that accepts storage entries using the imageguestpull driver witho...
