A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nSecurity Fix(es) :\n\n* A race condition flaw was found in the N_HLDC Linux kernel driver\nwhen accessing n_hdlc.tbuf list that can lead to double free. A local,\nunprivileged user able to set the HDLC line discipline on the tty\ndevice could use this flaw to increase their privileges on the system.\n(CVE-2017-2636, Important)\n\nRed Hat would like to thank Alexander Popov for reporting this issue.\n\nBug Fix(es) :\n\n* Previously, memory allocation in the libceph kernel module did not\nwork correctly. Consequently, the file system on a RADOS Block\nDevice(RBD) could become unresponsive in the situations under high\nmemory pressure. With this update, the underlying source code has been\nfixed, and the file system no longer hangs in the described scenario.\n(BZ#1418314)\n\n* Previously, the mpt3sas driver incorrectly checked the Transport\nLayer Retries (TLR) state even on Redundant Array Of Independent Discs\n(RAID) devices. Consequently, a kernel panic occurred when mpt3sas\nattempted to read from the RAID devices. With this update, mpt3sas has\nbeen fixed to check the TLR state only for non-RAID devices, and the\nkernel no longer panics under the described circumstances.\n(BZ#1427453)\"\n );\n

(BZ#1443497)\n\n* Previously, a kernel panic occurred when the mcelog daemon executed a huge page memory offline. This update fixes the HugeTLB feature of the Linux kernel to check for the Page Table Entry (PTE) NULL pointer in the page_check_address() function. As a result, the kernel panic no longer occurs under the described circumstances.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nThese updated kernel packages include several security issues and numerous bug fixes. Space precludes documenting all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article:\nhttps://access.redhat.com/articles/2986951.\n\nSecurity Fix(es) :\n\n* A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system.\n(CVE-2017-2636, Important)\n\n* A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt() system call. Users with non-namespace CAP_NET_ADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative.\nThis could adversely affect memory allocations and create situations where the system could crash or cause memory corruption.\n(CVE-2016-9793, Moderate)\n\n* A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory. (CVE-2017-2618, Moderate)\n\nRed Hat would like to thank Alexander Popov for reporting CVE-2017-2636 and Ralf Spenneberg for reporting CVE-2016-8650.

A local attacker with CAP_NET_RAW capability could\nuse this flaw to trigger a buffer overflow, resulting in the crash of\nthe system.

This could lead to memory corruption and possible privileged\nescalation. (CVE-2016-7910, Moderate)\n\n* A vulnerability was found in the Linux kernel. An unprivileged local\nuser could trigger oops in shash_async_export() by attempting to force\nthe in-kernel hashing algorithms into decrypting an empty data set.\n(CVE-2016-8646, Moderate)\n\n* It was reported that with Linux kernel, earlier than version\nv4.10-rc8, an application may trigger a BUG_ON in sctp_wait_for_sndbuf\nif the socket tx buffer is full, a thread is waiting on it to queue\nmore data, and meanwhile another thread peels off the association\nbeing used by the first thread.

If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is glibc-side mitigation which blocks processing of LD_LIBRARY_PATH for programs running in secure-execution mode and reduces the number of allocations performed by the processing of LD_AUDIT, LD_PRELOAD, and LD_HWCAP_MASK, making successful exploitation of this issue more difficult.\n (CVE-2017-1000366)\n\n - A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system.\n (CVE-2017-2636)\n\n - The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make these pointers point outside the array and cause an out-of- bounds memory access. A remote user or program could use this flaw to crash the kernel, resulting in denial of service.
