CVE-2024-26753
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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
