Linux Kernel

The InfiniBand (IB) implementation in the Linux kernel package before 2.6.32-504.12.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/.Show less

The implementation of certain splice_write file operations in the Linux kernel before 3.16 does not enforce a restriction on the maximum size of a single file, which allows local users to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted splice system call, as demonstrated by use of a file descriptor associated with an ext4 filesystem.Show less

Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.Show less

Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel before 3.18.2 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename.Show less

The em_sysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service (guest OS crash) by triggering use of a 16-bit code segment for emulation of a SYSENTER instruction.Show less

The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a parenthesized module template expression in the salg_name field, as demonstrated by the vfat(aes) expression, a different vulnerability than CVE-2013-7421.Show less

net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers.Show less

The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a module name in the salg_name field, a different vulnerability than CVE-2014-9644.Show less

Race condition in NVMap in NVIDIA Tegra Linux Kernel 3.10 allows local users to gain privileges via a crafted NVMAP_IOC_CREATE IOCTL call, which triggers a use-after-free error, as demonstrated by using a race condition to escape the Chrome sandbox.Show less

The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD.Show less

The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image.Show less

Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key.Show less

The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N. implementation in the Linux kernel through 3.18.1 uses an incorrect length field during a calculation of an amount of memory, which allows remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets.Show less

The rock_continue function in fs/isofs/rock.c in the Linux kernel through 3.18.1 does not restrict the number of Rock Ridge continuation entries, which allows local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image.Show less

The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address.Show less

drivers/misc/qseecom.c in the QSEECOM driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not validate certain offset, length, and base values within an ioctl call, which allows attackers to gain privileges or cause a denial of service (memory corruption) via a crafted application.Show less

arch/x86/kernel/entry_64.S in the Linux kernel before 3.17.5 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to gain privileges by triggering an IRET instruction that leads to access to a GS Base address from the wrong space.Show less

arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in the Linux kernel through 3.18.1 allows local users to bypass the espfix protection mechanism, and consequently makes it easier for local users to bypass the ASLR protection mechanism, via a crafted application that makes a set_thread_area system call and later reads a 16-bit value.Show less

The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value.Show less

The mdp_lut_hw_update function in drivers/video/msm/mdp.c in the MDP display driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not validate certain start and length values within an ioctl call, which allows attackers to gain privileges via a crafted application.Show less
