Linux Kernel contains a flaw in the mmc_ioctl_cdrom_read_data() function in drivers/cdrom/cdrom.c that may lead to the unauthorized disclosure of sensitive information. The issue is triggered when reading a block from the user's system, which can result in the associated buffer not being completely filled. This may allow a local attacker to gain access to arbitrary information stored within the kernel memory.


Location: Local Access Required
Attack Type: Information Disclosure, Input Manipulation
Version: Kernel 3.9.5
