Severity
Important
Notes
Title of the patch: Security update for kernel live patch 6
Description of the patch:
This kernel live patch for Linux Kernel 3.12.44-52.10.1 fixes security issues and bugs:
Security issues fixed:
- CVE-2015-8539: A negatively instantiated user key could have been used
by a local user to leverage privileges (bnc#958601).
- CVE-2015-6937: A NULL pointer dereference flaw was found in the Reliable
Datagram Sockets (RDS) implementation allowing a local user to cause
system DoS. A verification was missing that the underlying transport
exists when a connection was created. (bsc#953052)
- CVE-2015-7990: RDS: Verify the underlying transport exists before
creating a connection, preventing possible DoS (bsc#953052).
- CVE-2015-7872: Possible crash when trying to garbage collect an
uninstantiated keyring (bsc#951542).
- CVE-2015-2925: The prepend_path function in fs/dcache.c in the Linux
kernel did not properly handle rename actions inside a bind mount, which
allowed local users to bypass an intended container protection mechanism
by renaming a directory, related to a 'double-chroot attack (bnc#951625).
Non-security bugfix were also done:
- xfs: Fix lost direct IO write in the last block (bsc#954005).
- simple fix in kallsyms initialization (bsc#940342 bsc#916225)
