Stephan van Schaik, Alyssa Milburn, Sebastian Österlund, Pietro Frigo,
Kaveh Razavi, Herbert Bos, Cristiano Giuffrida, Giorgi Maisuradze, Moritz
Lipp, Michael Schwarz, Daniel Gruss, and Jo Van Bulck discovered that Intel
processors using Transactional Synchronization Extensions (TSX) could
expose memory contents previously stored in microarchitectural buffers to a
malicious process that is executing on the same CPU core. A local attacker
could use this to expose sensitive information. (CVE-2019-11135)
Deepak Gupta discovered that on certain Intel processors, the Linux kernel
did not properly perform invalidation on page table updates by virtual
guest operating systems. A local attacker in a guest VM could use this to
cause a denial of service (host system crash). (CVE-2018-12207)
Ori Nimron discovered that the AX25 network protocol implementation in the
Linux kernel did not properly perform permissions checks. A local attacker
could use this to create a raw socket. (CVE-2019-17052)
Ori Nimron discovered that the IEEE 802.15.4 Low-Rate Wireless network
protocol implementation in the Linux kernel did not properly perform
permissions checks. A local attacker could use this to create a raw socket.
(CVE-2019-17053)
Ori Nimron discovered that the Appletalk network protocol implementation in
the Linux kernel did not properly perform permissions checks. A local
attacker could use this to create a raw socket. (CVE-2019-17054)
Ori Nimron discovered that the modular ISDN network protocol implementation
in the Linux kernel did not properly perform permissions checks. A local
attacker could use this to create a raw socket. (CVE-2019-17055)
Ori Nimron discovered that the Near field Communication (NFC) network
protocol implementation in the Linux kernel did not properly perform
permissions checks. A local attacker could use this to create a raw socket.
(CVE-2019-17056)

(bsc#1135967)\n\n - CVE-2019-16231: drivers/net/fjes/fjes_main.c did not check the\n alloc_workqueue return value, leading to a NULL pointer dereference\n (bnc#1150466).\n\n - CVE-2019-18805: There was a net/ipv4/tcp_input.c signed integer overflow\n in tcp_ack_update_rtt() when userspace writes a very large integer to\n /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or\n possibly unspecified other impact, aka CID-19fad20d15a6 (bnc#1156187).\n\n - CVE-2019-17055: base_sock_create in drivers/isdn/mISDN/socket.c in the\n AF_ISDN network module did not enforce CAP_NET_RAW, which means that\n unprivileged users can create a raw socket, aka CID-b91ee4aa2a21\n (bnc#1152782).\n\n - CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs\n with Transactional Memory support could be used to facilitate\n sidechannel information leaks out of microarchitectural buffers, similar\n to the previously described 'Microarchitectural Data Sampling' attack.\n\n The Linux kernel was supplemented with the option to disable TSX\n operation altogether (requiring CPU Microcode updates on older systems)\n and better flushing of microarchitectural buffers (VERW).\n\n - CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a\n race condition in the Instruction Fetch Unit of the Intel CPU to cause a\n Machine Exception during Page Size Change, causing the CPU core to be\n non-functional.\n\n The Linux Kernel kvm hypervisor was adjusted to avoid page size changes\n in executable pages by splitting / merging huge pages into small pages as\n needed.\n\n - CVE-2019-10220: Added sanity checks on the pathnames passed to the user\n space. (bsc#1144903).\n\n The following non-security bugs were fixed:\n\n - ALSA: bebob: Fix prototype of helper function to return negative value\n (bsc#1051510).\n ...\n\n Description truncated.
