CVE-2017-15129

A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.

This kernel update is based on the upstream 4.4.111 and fixes several security issues.

The most important fix in this update is for the security issue named "Meltdown" that is fixed in theese kernels by enabling kernel Page Table Isolation (KTPI). Note that according to AMD, this issue does not effect Amd processors, so it is not enabled by default on systems using Amd CPU.

The list of known security fixes and mitigations in this kernel:

kvm: vmx: Scrub hardware GPRs at VM-exit. This enables partial mitigation in kvm for the security issue named "Spectre" (CVE-2017-5715, CVE-2017-5753).

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache (CVE-2017-5754, "Meltdown").

Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely (CVE-2017-15129).

The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h (CVE-2017-17741).

The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (CVE-2017-1000407).

The kernels are also fixed to allow loading cpu microcode for Amd family 17 (Zen) processors, and dracut have been fixed to properly support early firmware loading on the microcode on all Amd cpus.

This kernel-linus update is based on the upstream 4.14.18 and adds some support for mitigating Spectre, variant 1 (CVE-2017-5753) and as it is built with the retpoline-aware gcc-5.5.0-1.mga6, it now provides full retpoline mitigation for Spectre, variant 2 (CVE-2017-5715).

The BPF interpreter has been used as part of the spectre 2 attack CVE-2017-5715. To make attacker job harder introduce BPF_JIT_ALWAYS_ON config option that removes interpreter from the kernel in favor of JIT-only mode. This is now enabled by default in Mageia kernels.

Other security fixes in this update:

Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner (CVE-2017-1000410).

• CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service (bnc#1073928).

• CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allowed local users to obtain potentially sensitive address information, aka a 'pointer leak (bnc#1073928).

• CVE-2017-17975: Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c allowed attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure (bnc#1074426).

• CVE-2017-18017: The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488).

• CVE-2017-18174: In the Linux kernel the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free (bnc#1080533).

• CVE-2017-18208: The madvise_willneed function in mm/madvise.c allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494).
