linux-toradex.git/include/crypto/kpp.h, branch v5.1-rc1 Linux kernel for Apalis and Colibri modules crypto: user - fix use_after_free of struct xxx_request 2018-12-07T06:15:00+00:00 Corentin Labbe clabbe@baylibre.com 2018-11-29T14:42:21+00:00 f7d76e05d058b832b373237566cc1af8251371b5 All crypto_stats functions use the struct xxx_request for feeding stats, but in some case this structure could already be freed. For fixing this, the needed parameters (len and alg) will be stored before the request being executed.
