This update for the Linux Kernel 3.12.51-52.34.1 fixes the following issues:
- CVE-2016-2384: A malicious USB device could cause a kernel crash in
the alsa usb-audio driver. (bsc#967773)
- CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when
the network was considered congested. The kernel would incorrectly
misinterpret the congestion as an error condition and incorrectly
free/clean up the skb. When the device would then send the skb's queued,
these structures would be referenced and may panic the system or allow
an attacker to escalate privileges in a use-after-free scenario. (bsc#966683)
- CVE-2016-0774: A pipe b
This kernel live patch for Linux Kernel 3.12.51-52.34.1 fixes two security
issues:
Fixes:
- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in
the Linux kernel allowed local users to bypass intended AF_UNIX socket
permissions or cause a denial of service (panic) via crafted epoll_ctl
calls. (bsc#955837)
This kernel live patch for Linux Kernel 3.12.51-52.34.1 fixes one security issue:
- A reference leak in keyring handling with join_session_keyring() could lead
to local attackers gain root privileges. (bsc#962075, CVE-2016-0728).
The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes.
Following security bugs were fixed:
- CVE-2015-7550: A local user could have triggered a race between read and revoke in keyctl (bnc#958951).
- CVE-2015-8539: A negatively instantiated user key could have been used by a local user to leverage privileges (bnc#958463).
- CVE-2015-8543: The networking implementation in the Linux kernel did not validate protocol identifiers for certain protocol families, which allowed local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE
