Summary

NetBSD Signed Integer Overflow in cryptodev_op via cryptodev.c

Details

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