CVE-2026-98387

A flaw was found in the Linux kernel's s390 cryptographic subsystem. Missing error code verification during AES Advanced Encryption Standard cipher operations allows data processing loops to execute even if setup fails. A local user could exploit this vulnerability during cryptographic operations...

Linux kernel Cryptographic Subsystem Heap Buffer Overflow DoS

The vulnerability in the aeadrecvmsg function within the crypto/algifaead.c module of the Linux kernel’s cryptographic subsystem is related to synchronization errors that occur when a shared resource is utilized “race condition”. Exploitation of this vulnerability may allow an attacker to...

CVE-2026-97588

A flaw was found in the Linux kernel's s390 cryptographic subsystem. This vulnerability allows a local user to cause a Denial of Service DoS by executing cryptographic operations when underlying hardware repeatedly reports a busy state. Because the subsystem fails to properly translate persistent...

Linux kernel Cryptographic Buffer Overflow

The vulnerability in the x509processextension function within the crypto/asymmetrickeys/x509certparser.c file of the Linux kernel cryptographic subsystem involves buffer overflow. Exploitation of this vulnerability could allow an attacker to compromise the confidentiality and availability of...

USN-8620-1: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...
