Description
A denial of service flaw was discovered in the Btrfs file system in the
Linux kernel. A local user could cause a denial of service by creating a
large number of files with names that have the same CRC32 hash value.
A denial of service flaw was discovered in the Btrfs file system in the
Linux kernel. A local user could cause a denial of service (prevent file
creation) for a victim, by creating a file with a specific CRC32C hash
value in a directory important to the victim.
Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that
allows for privilege escalation. A local user could exploit this flaw to
run commands as root when using the perf tool.
A flaw was discovered in the Xen subsystem of the Linux kernel when it
provides read-only access to a disk that supports TRIM or SCSI UNMAP to a
guest OS. A privileged user in the guest OS could exploit this flaw to
destroy data on the disk, even though the guest OS should not be able to
write to the disk.
A flaw was discovered in the Linux kernel when an IPv6 socket is used to
connect to an IPv4 destination. An unprivileged local user could exploit
this flaw to cause a denial of service (system crash).
An information leak was discovered in the IPSec key_socket implementation
in the Linux kernel. An local user could exploit this flaw to examine
potentially sensitive information in kernel memory.
Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the
Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a
denial of service (system crash).
Hannes Frederic Sowa discovered a flaw in the IPv6 subsystem of the Linux
kernel when the IPV6_MTU setsockopt option has been specified in
combination with the UDP_CORK option. A local user could exploit this flaw
to cause a denial of service (system crash).
