CVE-2026-53016
crypto: ccp - copy IV using skcipher ivsize
Description

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.

Solution
Fix an out-of-bounds copy in the CCP driver when handling AES-CTR IVs.
  • Use crypto_skcipher_ivsize() to copy IVs.
  • Ensure IV size matches algorithm requirements.
  • Update the Linux kernel to the patched version.
