Descriptions

In the Linux kernel, the following vulnerability has been resolved: crypto: virtio/akcipher - Fix stack overflow on memcpy sizeof(struct virtio_crypto_akcipher_session_para) is less than
sizeof(struct virtio_crypto_op_ctrl_req::u), copying more bytes from
stack variable leads stack overflow. Clang reports this issue by
commands:
make -j CC=clang-14 mrproper >/dev/null 2>&1
make -j O=/tmp/crypto-build CC=clang-14 allmodconfig >/dev/null 2>&1
make -j O=/tmp/crypto-build W=1 CC=clang-14 drivers/crypto/virtio/ virtio_crypto_akcipher_algs.o

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: virtio/akcipher: corrige el desbordamiento de pila en memcpy sizeof(struct virtio_crypto_akcipher_session_para) es menor que sizeof(struct virtio_crypto_op_ctrl_req::u), copiar más bytes de la variable de pila provoca el desbordamiento de pila. Clang informa este problema mediante comandos: make -j CC=clang-14 mrproper >/dev/null 2>&1 make -j O=/tmp/crypto-build CC=clang-14 allmodconfig >/dev/null 2>&1 make -j O=/tmp/crypto-build W=1 CC=clang-14 drivers/crypto/virtio/ virtio_crypto_akcipher_algs.o
