Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: For GRE packets, tunnelcsumstart is used instead of the transport header. For GRE packets with TUNNELCSUM, a local checksum offload is applied to CHECKSUMPARTIAL packets. The ipGRExmit function must validate csumstart after an...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

openssl: openssl: Information Disclosure from Uninitialized Memory via Invalid RSA Public Key

A flaw was found in openssl. Applications that use RSASVE key encapsulation, a method for securely exchanging encryption keys, may inadvertently expose sensitive data. This vulnerability arises when an application processes a malicious, invalid RSA public key provided by an attacker without prope...

Key Encapsulation Mechanism-Based Integrated Encryption Scheme (KEM-IES)

The Elliptic Curve Integrated Encryption Scheme ECIES is widely regarded as a practical method and has been adopted by multiple standards. However, the advancement of quantum computing technologies poses potential security risks to ECIES. Therefore, this study proposes a Key Encapsulation...

CVE-2026-43456

A flaw was found in the Linux kernel's bonding driver. When a non-Ethernet device, such as a Generic Routing Encapsulation GRE tunnel, is added to a bond, a type confusion vulnerability occurs. This happens because the bonding driver incorrectly copies network header operations from the slave...
