Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp – Check for page allocation failure correctly in TIO Sashiko notes: If snpallocfirmwarepages returns NULL under memory pressure, is it safe to pass it directly to pageaddress? On architectures without HASHEDPAGEVIRTUA...

CVE-2026-74404

A flaw was found in the Linux kernel's crypto: ccp component. An off-by-one error in the snpfilterreservedmemregions function can lead to a heap buffer overflow. This vulnerability could allow an attacker to corrupt memory, potentially leading to a denial of service or arbitrary code execution...

CVE-2026-74403

A flaw was found in the Linux kernel's Cryptographic Co-processor CCP driver. Under memory pressure, if a page allocation fails, the driver incorrectly processes the allocation result. This can lead to the dereferencing of an invalid memory address, potentially causing a system crash or other...

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...
