NVD Description

Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

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.
