The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247.Show less

The generic_file_splice_write function in fs/splice.c in the Linux kernel before 2.6.19 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory, a different vulnerability than CVE-2008-4210.Show less

fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool.Show less

fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O.Show less

The error-reporting functionality in (1) fs/ext2/dir.c, (2) fs/ext3/dir.c, and possibly (3) fs/ext4/dir.c in the Linux kernel 2.6.26.5 does not limit the number of printk console messages that report directory corruption, which allows physically proximate attackers to cause a denial of service (temporary system hang) by mounting a filesystem that has corrupted dir->i_size and dir->i_blocks values and performing (a) read or (b) write operations. NOTE: there are limited scenarios in which this crosses privilege boundaries.Show less

The sctp_getsockopt_hmac_ident function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4, when the SCTP-AUTH extension is enabled, relies on an untrusted length value to limit copying of data from kernel memory, which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function.Show less

The proc_do_xprt function in net/sunrpc/sysctl.c in the Linux kernel 2.6.26.3 does not check the length of a certain buffer obtained from userspace, which allows local users to overflow a stack-based buffer and have unspecified other impact via a crafted read system call for the /proc/sys/sunrpc/transports file.Show less

net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4 does not verify that the SCTP-AUTH extension is enabled before proceeding with SCTP-AUTH API functions, which allows attackers to cause a denial of service (NULL pointer dereference and panic) via vectors that result in calls to (1) sctp_setsockopt_auth_chunk, (2) sctp_setsockopt_hmac_ident, (3) sctp_setsockopt_auth_key, (4) sctp_setsockopt_active_key, (5) sctp_setsockopt_del_key, (6) sctp_getsockopt_maxburst, (7) sctp_getsockopt_active_key, (8) sctp_getsockopt_peer_auth_chunks, or (9) sctp_getsockopt_local_auth_chunks.Show less

The sbni_ioctl function in drivers/net/wan/sbni.c in the wan subsystem in the Linux kernel 2.6.26.3 does not check for the CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE ioctl request, which allows local users to bypass intended capability restrictions.Show less

Integer overflow in the sctp_setsockopt_auth_key function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel 2.6.24-rc1 through 2.6.26.3 allows remote attackers to cause a denial of service (panic) or possibly have unspecified other impact via a crafted sca_keylength field associated with the SCTP_AUTH_KEY option.Show less

Integer overflow in the dccp_setsockopt_change function in net/dccp/proto.c in the Datagram Congestion Control Protocol (DCCP) subsystem in the Linux kernel 2.6.17-rc1 through 2.6.26.2 allows remote attackers to cause a denial of service (panic) via a crafted integer value, related to Change L and Change R options without at least one byte in the dccpsf_val field.Show less

The rt6_fill_node function in net/ipv6/route.c in Linux kernel 2.6.26-rc4, 2.6.26.2, and possibly other 2.6.26 versions, allows local users to cause a denial of service (kernel OOPS) via IPv6 requests when no IPv6 input device is in use, which triggers a NULL pointer dereference.Show less

The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.Show less

Off-by-one error in the iov_iter_advance function in mm/filemap.c in the Linux kernel before 2.6.27-rc2 allows local users to cause a denial of service (system crash) via a certain sequence of file I/O operations with readv and writev, as demonstrated by testcases/kernel/fs/ftest/ftest03 from the Linux Test Project.Show less

The shmem_delete_inode function in mm/shmem.c in the tmpfs implementation in the Linux kernel before 2.6.26.1 allows local users to cause a denial of service (system crash) via a certain sequence of file create, remove, and overwrite operations, as demonstrated by the insserv program, related to allocation of "useless pages" and improper maintenance of the i_blocks count.Show less

The snd_seq_oss_synth_make_info function in sound/core/seq/oss/seq_oss_synth.c in the sound subsystem in the Linux kernel before 2.6.27-rc2 does not verify that the device number is within the range defined by max_synthdev before returning certain data to the caller, which allows local users to obtain sensitive information.Show less

Buffer overflow in format descriptor parsing in the uvc_parse_format function in drivers/media/video/uvc/uvc_driver.c in uvcvideo in the video4linux (V4L) implementation in the Linux kernel before 2.6.26.1 has unknown impact and attack vectors.Show less
