Vulnerability Title
NetBSD Signed Integer Overflow in cryptodev_op via cryptodev.c
Vulnerability Description
NetBSD prior to commit ec8451e contains a signed integer overflow vulnerability in the cryptodev_op() function in sys/opencrypto/cryptodev.c where the local variable iov_len is declared as a signed int but assigned from an unsigned cop->dst_len value, causing undefined behavior when cop->dst_len exceeds INT_MAX. A local attacker with access to /dev/crypto and a compression session type can exploit this vulnerability by providing a dst_len value exceeding INT_MAX to trigger a kernel panic through NULL pointer dereference when CONFIG_SVS is disabled and corrupted UIO pointer arithmetic.

Vulnerability Title
NetBSD 输入验证错误漏洞
Vulnerability Description
NetBSD是NetBSD基金会的一套开源的类Unix操作系统。 NetBSD ec8451之前版本存在输入验证错误漏洞,该漏洞源于cryptodev_op函数中局部变量iov_len声明为有符号整数但赋值来自无符号值,可能导致有符号整数溢出。
