Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, information leak or data loss. CVE-2013-4312 Tetsuo Handa discovered that users can use pipes queued on local sockets to allocate an unfair share of kernel memory, leading to denial-of-service . This issue was previously mitigated for the stable suite by limiting the total number of files queued by each user on local sockets. The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user. CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. CVE-2015-8767 An SCTP denial-of-service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake. CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service . CVE-2015-8812 A flaw was found in the iw_cxgb3 Infiniband driver. Whenever it could not send a packet because the network was congested, it would free the packet buffer but later attempt to send the packet again. This use-after-free could result in a denial of service , data loss or privilege escalation. CVE-2015-8816 A use-after-free vulnerability was discovered in the USB hub driver. This may be used by a physically present user for privilege escalation. CVE-2015-8830 Ben Hawkes of Google Project Zero reported that the AIO interface permitted reading or writing 2 GiB of data or more in a single chunk, which could lead to an integer overflow when applied to certain filesystems, socket or device types. The full security impact has not been evaluated. CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial-of-service. CVE-2016-0774 It was found that the fix for CVE-2015-1805 in kernel versions older than Linux 3.16 did not correctly handle the case of a partially failed atomic read. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space. CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks on an x86 system. On an SMP system this could possibly lead to a crash, information leak or privilege escalation. CVE-2016-2384 Andrey Konovalov found that a crafted USB MIDI device with an invalid USB descriptor could trigger a double-free. This may be used by a physically present user for privilege escalation. CVE-2016-2543 Dmitry Vyukov found that the core sound sequencer driver lacked a necessary check for a null pointer, allowing a user with access to a sound sequencer device to cause a denial-of- service . CVE-2016-2544, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548 Dmitry Vyukov found various race conditions in the sound subsystem "s management of timers. A user with access to sound devices could use these to cause a denial-of-service or possibly for privilege escalation. CVE-2016-2545 Dmitry Vyukov found a flaw in list manipulation in the sound subsystem "s management of timers. A user with access to sound devices could use this to cause a denial-of-service or possibly for privilege escalation. CVE-2016-2549 Dmitry Vyukov found a potential deadlock in the sound subsystem "s use of high resolution timers. A user with access to sound devices could use this to cause a denial-of-service . CVE-2016-2550 The original mitigation of CVE-2013-4312, limiting the total number of files a user could queue on local sockets, was flawed. A user given a local socket opened by another user, for example through the systemd socket activation mechanism, could make use of the other user"s quota, again leading to a denial-of-service . This is fixed by accounting queued files to the sender rather than the socket opener.
