CVE-2015-5257

drivers/usb/serial/whiteheat.c in the Linux kernel before 4.2.4 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted USB device. NOTE: this ID was incorrectly used for an Apache Cordova issue that has the correct ID of CVE-2015-8320.

This kernel update is based on the upstream 4.1.12 longterm kernel and fixes at least the following security issue:

Moein Ghasemzadeh discovered that the USB WhiteHEAT serial driver contained hardcoded attributes about the USB devices. An attacker could construct a fake WhiteHEAT USB device that, when inserted, causes a denial of service (system crash) (CVE-2015-5257).

It also fixes various upstream bugs, for more info see the referenced changelogs.

This kernel-tmb update provides an upgrade to the upstream 4.1 longterm kernel series, currently based on 4.1.15 and resolves at least the following security issues:

It was found that the Linux kernel's keyring implementation would leak memory when adding a key to a keyring via the add_key() function. A local attacker could use this flaw to exhaust all available memory on the system. (CVE-2015-1333)

A flaw was found in the Linux kernel where the deletion of a file or directory could trigger an unmount and reveal data under a mount point. This flaw was inadvertently introduced with the new feature of being able to lazily unmount a mount tree when using file system user namespaces. (CVE-2015-4176)

A flaw was discovered in the kernel's collect_mounts function. If the kernel audit subsystem called collect_mounts to audit an unmounted path, it could panic the system. With this flaw, an unprivileged user could call umount (MNT_DETACH) to launch a denial-of-service attack. (CVE-2015-4177)

A flaw was found in the Linux kernel which is related to the user namespace lazily unmounting file systems. The fs_pin struct has two members (m_list and s_list) which are usually initialized on use in the pin_insert_group function. However, these members might go unmodified; in this case, the system panics when it attempts to destroy or free them. This flaw could be used to launch a denial-of-service attack. (CVE-2015-4178)

A DoS flaw was found for a Linux kernel built for the x86 architecture which had the KVM virtualization support(CONFIG_KVM) enabled. The kernel would be vulnerable to a NULL pointer dereference flaw in Linux kernel's kvm_apic_has_events() function while doing an ioctl. An unprivileged user able to access the "/dev/kvm" device could use this flaw to crash the system kernel. (CVE-2015-4692)

A flaw was found in the kernel's implementation of the Berkeley Packet Filter (BPF). A local attacker could craft BPF code to crash the system by creating a situation in which the JIT compiler would fail to correctly optimize the JIT image on the last pass. This would lead to the CPU executing instructions that were not part of the JIT code. (CVE-2015-4700)

The virtnet_probe function in drivers/net/virtio_net.c in the Linux kernel before 4.2 attempts to support a FRAGLIST feature without proper memory allocation, which allows guest OS users to cause a denial of service (buffer overflow and memory corruption) via a crafted sequence of fragmented packets. (CVE-2015-5156)

Moein Ghasemzadeh discovered that the USB WhiteHEAT serial driver contained hardcoded attributes about the USB devices. An attacker could construct a fake WhiteHEAT USB device that, when inserted, causes a denial of service (system crash) (CVE-2015-5257).

A guest to host DoS issue was found affecting various hypervisors. In that, a guest can DoS the host by triggering an infinite stream of "alignment check" (#AC) exceptions. This causes the microcode to enter an infinite loop where the core never receives another interrupt. The host kernel panics due to this effect (CVE-2015-5307).

The get_bitmap_file function in drivers/md/md.c in the Linux kernel before 4.1.6 does not initialize a certain bitmap data structure, which allows local users to obtain sensitive information from kernel memory via a GET_BITMAP_FILE ioctl call. (CVE-2015-5697)

Use-after-free vulnerability in the path_openat function in fs/namei.c in the Linux kernel 3.x and 4.x before 4.0.4 allows local users to cause a denial of service or possibly have unspecified other impact via O_TMPFILE filesystem operations that leverage a duplicate cleanup operation. (CVE-2015-5706)

It was discovered that an integer overflow error existed in the SCSIgeneric (sg) driver in the Linux kernel. A local attacker with writepermission to a SCSI generic device could use this to cause a denial of service (system crash) or potentially escalate their privileges. (CVE-2015-5707)

The __rds_conn_create function in…

This kernel update provides an upgrade to the upstream 4.4 longterm kernel series, currently based on 4.4.13 and resolves at least the following security issues:

The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (CVE-2013-4312).

drivers/usb/serial/whiteheat.c in the Linux kernel before 4.2.4 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted USB device (CVE-2015-5257).

The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c (CVE-2015-5307).

An out-of-bounds memory read was found, affecting kernels from 4.3-rc1 onwards. This vulnerability was caused by incorrect X.509 time validation in x509_decode_time() function in x509_cert_parser.c (CVE-2015-5327).

The __rds_conn_create function in net/rds/connection.c in the Linux kernel through 4.2.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound (CVE-2015-6937).

The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 does not ensure that certain slot numbers are valid, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (CVE-2015-7799).

The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c (CVE-2015-8104).

The networking implementation in the Linux kernel through 4.3.3, as used in Android and other products, does not validate protocol identifiers for certain protocol families, which allows local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application (CVE-2015-8543).

An issue with ASN.1 DER decoder was reported that could lead to memory corruptions, possible privilege escalation, or complete local denial of service via x509 certificate DER files (CVE-2016-0758).

The evm_verify_hmac function in security/integrity/evm/evm_main.c in the Linux kernel before 4.5 does not properly copy data, which makes it easier for local users to forge MAC values via a timing side-channel attack (CVE-2016-2085).

The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data (CVE-2016-2117).

The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors (CVE-2016-3136).
