CVE-2026-9076 Out-of-Bounds Read in CMS Password-Based Decryption

Issue summary: When CMS password-based decryption RFC 3211 / PWRI key unwrap processes attacker-supplied CMS data, an attacker-chosen stream-mode KEK cipher can trigger a heap out-of-bounds read in kekunwrapkey. Impact summary: A heap buffer over-read may trigger a crash which leads to Denial of...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

PT-2026-60830

NIST Special Publication 800-38D specifies that the bit length of the AAD shall not exceed 2^64 - 1 bits. The implementation of AES-GCM in libcrux-aesgcm neither enforced this limit for encryption nor for decryption. Impact Use of AES-GCM with AAD of length exceeding the prescribed maximum length...
