Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.
CVE-2018-6554
A memory leak in the irda_bind function in the irda subsystem was
discovered. A local user can take advantage of this flaw to cause a
denial of service (memory consumption).
CVE-2018-6555
A flaw was discovered in the irda_setsockopt function in the irda
subsystem, allowing a local user to cause a denial of service
(use-after-free and system crash).
CVE-2018-7755
Brian Belleville discovered a flaw in the fd_locked_ioctl function
in the floppy driver in the Linux kernel. The floppy driver copies a
kernel pointer to user memory in response to the FDGETPRM ioctl. A
local user with access to a floppy drive device can take advantage
of this flaw to discover the location kernel code and data.
