Linux kernel is vulnerable to denial of service(DoS) attacks. blk_rq_map_user_iov() function in the Linux kernel’s block device implementation does not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a use-after-free by leveraging write access to a /dev/sg device.
