kernel: crypto: ccp - Fix a crash due to incorrect cleanup usage of kfree

A flaw was found in the Linux kernel's crypto: ccp module. An incorrect cleanup usage of the kfree function, which is used for memory deallocation, with a local pointer variable could lead to an invalid deallocation of a stack address. This issue can result in a system crash, causing a Denial of...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

The vulnerability of the ccp_aes_complete() function in the drivers/crypto/ccp/ccp-crypto-aes.c module of the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ccpaescomplete function in the drivers/crypto/ccp/ccp-crypto-aes.c module of the Linux kernel is related to the copying of buffers without checking the input data. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

CVE-2026-80652

A flaw was found in the Linux kernel's Cryptographic Co-processor CCP driver. A local attacker could trigger a kernel crash, leading to a denial of service DoS, by providing a zero-length certificate chain buffer during a Platform Dynamic Hardware PDH export operation. This issue specifically...
