The unw_unwind_to_user function in unwind.c on Itanium (ia64) architectures in Linux kernel 2.6 allows local users to cause a denial of service (system crash).

Linux kernel 2.6 on Itanium (ia64) architectures allows local users to cause a denial of service via a "missing Itanium syscall table entry."

Linux kernel before 2.6.9, when running on the AMD64 and Intel EM64T architectures, allows local users to write to privileged IO ports via the OUTS instruction.

Unknown vulnerability in Linux kernel 2.4.x, 2.5.x, and 2.6.x allows NFS clients to cause a denial of service via O_DIRECT.

Netfilter in Linux kernel 2.6.8.1 allows remote attackers to cause a denial of service (kernel crash) via crafted IP packet fragments.

Netfilter in the Linux kernel 2.6.8.1 allows local users to cause a denial of service (memory consumption) via certain packet fragments that are reassembled twice, which causes a data structure to be allocated twice.

The ext2_make_empty function call in the Linux kernel before 2.6.11.6 does not properly initialize memory when creating a block for a new directory entry, which allows local users to obtain potentially sensitive information by reading the block.

The netfilter/iptables module in Linux before 2.6.8.1 allows remote attackers to cause a denial of service (kernel crash) or bypass firewall rules via crafted packets, which are not properly handled by the skb_checksum_help function.

Linux kernel 2.6.10 and 2.6.11rc1-bk6 uses different size types for offset arguments to the proc_file_read and locks_read_proc functions, which leads to a heap-based buffer overflow when a signed comparison causes negative integers to be used in a po...

Signedness error in the copy_from_read_buf function in n_tty.c for Linux kernel 2.6.10 and 2.6.11rc1 allows local users to read kernel memory via a negative argument.
