Summary

Use-after-free vulnerability in the path_openat function in fs/namei.c in the Linux kernel 3.x and 4.x before 4.0.4 allows local users to cause a denial of service or possibly have unspecified other impact via O_TMPFILE filesystem operations that leverage a duplicate cleanup operation.

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leak.

  - CVE-2015-1333
    Colin Ian King discovered a flaw in the add_key function
    of the Linux kernel's keyring subsystem. A local user
    can exploit this flaw to cause a denial of service due
    to memory exhaustion.

  - CVE-2015-3212
    Ji Jianwen of Red Hat Engineering discovered a flaw in
    the handling of the SCTPs automatic handling of dynamic
    multi-homed connections. A local attacker could use this
    flaw to cause a crash or potentially for privilege
    escalation.

  - CVE-2015-4692
    A NULL pointer dereference flaw was found in the
    kvm_apic_has_events function in the KVM subsystem. A
    unprivileged local user could exploit this flaw to crash
    the system kernel resulting in denial of service.

  - CVE-2015-4700
    Daniel Borkmann discovered a flaw in the Linux kernel
    implementation of the Berkeley Packet Filter which can
    be used by a local user to crash the system.

  - CVE-2015-5364
    It was discovered that the Linux kernel does not
    properly handle invalid UDP checksums. A remote attacker
    could exploit this flaw to cause a denial of service
    using a flood of UDP packets with invalid checksums.

  - CVE-2015-5366
    It was discovered that the Linux kernel does not
    properly handle invalid UDP checksums. A remote attacker
    can cause a denial of service against applications that
    use epoll by injecting a single packet with an invalid
    checksum.

  - CVE-2015-5697
    A flaw was discovered in the md driver in the Linux
    kernel leading to an information leak.

  - CVE-2015-5706
    An user triggerable use-after-free vulnerability in path
    lookup in the Linux kernel could potentially lead to
    privilege escalation.

  - CVE-2015-5707
    An integer overflow in the SCSI generic driver in the
    Linux kernel was discovered. A local user with write
    permission on a SCSI generic device could potentially
    exploit this flaw for privilege escalation."
