High [CVE-2026-53016] ccp - copy IV using skcipher ivsize
CVE-2026-53016Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - copy IV using skcipher ivsize AF_ALG rfc3686-ctr-aes-ccp requests pass an 8-byte IV to the driver. ccp_aes_complete() restores AES_BLOCK_SIZE bytes into the caller's IV buffer while RFC3686 skciphers expose an 8-byte IV, so the restore overruns the provided buffer. Use crypto_skcipher_ivsize() to copy only the algorithm's IV length. When processing AF_ALG rfc3686-ctr-aes-ccp requests, the ccp_aes_complete() 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 result in memory corruption within the kernel. An out-of-bounds write exists in the AMD CCP AES completion path because ccp_aes_complete() restores…
