CVE-2026-74404 crypto: ccp - Fix snp_filter_reserved_mem_regions() off-by-one

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Fix snpfilterreservedmemregions off-by-one Sashiko notes: regarding the bounds check in snpfilterreservedmemregions called via walkiomemresdesc: does the check if rangelist-numelements 16 + 8 PAGESIZE allow an...

CVE-2026-74403

The CVE-2026-74403 entries describe a Linux kernel fix in crypto: ccp where a NULL page allocation could lead to a non-NULL garbage from page_address(NULL) on architectures without HASHED_PAGE_VIRTUAL. The root cause is passing a potentially NULL page pointer to page_address() and then evaluating...

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...
