The fill_write_buffer function in sysfs/file.c in Linux kernel 2.6.12 up to versions before 2.6.17-rc1 does not zero terminate a buffer when a length of PAGE_SIZE or more is requested, which might allow local users to cause a denial of service (crash) by causing an out-of-bounds read.

Linux kernel 2.6.16-rc2 and earlier, when running on x86_64 systems with preemption enabled, allows local users to cause a denial of service (oops) via multiple ptrace tasks that perform single steps, which can cause corruption of the DEBUG_STACK stack during the do_debug function call.

Integer overflow in the do_replace function in netfilter for Linux before 2.6.16-rc3, when using "virtualization solutions" such as OpenVZ, allows local users with CAP_NET_ADMIN rights to cause a buffer overflow in the copy_from_user function.

The ip_push_pending_frames function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan (nmap -sI) attack, which bypasses intended protections against such attacks.

Race condition in the (1) add_key, (2) request_key, and (3) keyctl functions in Linux kernel 2.6.x allows local users to cause a denial of service (crash) or read sensitive kernel memory by modifying the length of a string argument between the time that the kernel calculates the length and when it copies the data into kernel memory.

sys_mbind in mempolicy.c in Linux kernel 2.6.16 and earlier does not sanity check the maxnod variable before making certain computations for the get_nodes function, which has unknown impact and attack vectors.

Linux kernel before 2.6.15.3 down to 2.6.12, while constructing an ICMP response in icmp_send, does not properly handle when the ip_options_echo function in icmp.c fails, which allows remote attackers to cause a denial of service (crash) via vectors such as (1) record-route and (2) timestamp IP options with the needaddr bit set and a truncated value.

Buffer overflow in the MoxaDriverIoctl function for the moxa serial driver (moxa.c) in Linux 2.2.x, 2.4.x, and 2.6.x before 2.6.22 allows local users to execute arbitrary code via a certain modified length value.
