CVE-2014-4322
HIGH7.2

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.

CVE-2014-8133
LOW2.1

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.

CVE-2014-9419
LOW2.1

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.

CVE-2014-9420
MEDIUM4.9

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.

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.

LOW3.6

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.

MEDIUM4.9

The UDF filesystem implementation in the Linux kernel before 3.18.2 does not validate certain lengths, which allows local users to cause a denial of service (buffer over-read and system crash) via a crafted filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c.
