CVE-2026-63940

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV module. This vulnerability occurs because the system does not properly handle Port I/O requests with a length of zero. An attacker, potentially from a guest virtual machine, could exploit...

CVE-2026-63938

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV feature. When processing Page State Change PSC requests, the system does not properly validate the PSC buffer against the effective size of the scratch area. This can occur if a guest...

CVE-2026-63939

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV support. This vulnerability arises from an incorrect calculation of the maximum length for the in-Guest-Host Communication Block GHCB scratch area. When processing Page State Change PS...

CVE-2026-63937

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV. This time-of-check to time-of-use TOCTOU vulnerability exists when KVM processes the guest-accessible Page State Change PSC buffer. A misbehaving guest could exploit this timing issue...

CVE-2026-16317 Silent Drop of TLS 1.3 Encrypted Records in s2n-tls

Missing validation of the outer contenttype byte on TLS 1.3 encrypted records in s2n-tls allows an active man-in-the-middle to silently discard individual application data records without either endpoint detecting the modification. RFC 8446 Section 5.2 requires that the outer contenttype of all...

CVE-2026-16317

The flaw affects s2n-tls (TLS 1.3) where the outer content_type byte is not covered by the AEAD tag because it is hardcoded in AAD instead of using the wire byte. This allows an active MITM to silently discard individual application_data records without detection, enabling selective suppression o...

SUSE CVE-2026-63940

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Ignore Port I/O requests of length '0' Explicitly ignore Port I/O requests of length '0' or count '0', so that setting up the software scratch area and other code doesn't have to worry about underflowing the length, and...

kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp

A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP implementation. A remote Bluetooth Low Energy BLE device can exploit this by sending a specially crafted L2CAP ECRED reconfiguration response. This can lead to the corruption of the channel list,...

Investigation of STEEP for Secure Communications over SIMO and MISO Channels Subject to Full-Duplex Jamming and Eavesdropping

Secure communications over SIMO and MISO channels between wireless nodes are commonly encountered in applications and widely considered in the literature. This paper investigates such a problem by considering a newly proposed scheme called secrecy-message transmission by echoing encrypted probes...

Amazon Linux 2 : golang, --advisory ALAS2-2026-3819 (ALAS-2026-3819)

The version of golang installed on the remote host is prior to 1.25.12-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3819 advisory. On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final...
