CVE-2026-53170

A flaw was found in the Linux kernel's accel/ethosu driver. A local attacker could exploit a vulnerability where DMA commands with uninitialized length are not properly handled. By omitting a specific DMA length setup command and issuing a DMA start command, a user could bypass bounds checks,...

Name of the Vulnerable Software and Affected Versions Envoy versions prior to 1.35.11 Envoy versions prior to 1.36.7 Envoy versions prior to 1.37.3 Envoy versions prior to 1.38.1 Description An issue exists in the UDP DNS filter when configured with local or remote resolution for names exactly 25...

RHEL 10 : kernel (RHSA-2026:30129)

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:30129 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: rxrpc: fix RESPONSE...

The vulnerability of the mm/mempool module in Linux operating systems allows a hacker to cause a service failure or memory corruption.

The vulnerability of the mm/mempool module in Linux operating systems is related to access to a buffer with an incorrect length value. Exploiting this vulnerability can allow an attacker to cause service failures or memory corruption...

Curl 8.18.0 < 8.21.0 QUIC Zero-Length UDP Datagrams DoS

The version of curl installed on the remote host is 8.18.0 prior to 8.21.0. It is, therefore, affected by a denial of service vulnerability: - An issue in curl's QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service by continuously streaming empty...

PT-2026-52951

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the RISC-V IOMMU invalidation path. Because RISC-V supports sign extended page tables, a gather-end value of ULONG MAX can cause an infinite loop due to an integer...

CVE-2026-53246

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...

kernel: RDMA/mana: Validate rx_hash_key_len

A flaw was found in the Linux kernel's RDMA/mana component. A local user could exploit this vulnerability by providing an invalid rxhashkeylen value through a user-space API uAPI structure. This invalid value is then used in a memcpy operation without proper bounds checking, allowing the user to...

CVE-2026-6331

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...

CVE-2026-8720

wcBlake2bHmacFinal and wcBlake2sHmacFinal discard the message when the key length exceeds the block size, producing a MAC that is independent of the input. When the supplied key is longer than the BLAKE2 block size the key-hashing branch reinitialized the running hash state, discarding the...

CVE-2026-6329

PKCS12 MAC verification uses an attacker-controlled comparison length, weakening the integrity check on the MAC and allowing a mismatched MAC to be accepted. The PKCS12 verify path compared the locally computed HMAC against the MAC parsed from the PKCS12 structure using a length taken directly fr...
