The ABI in the Linux kernel 2.6.28 and earlier on s390, powerpc, sparc64, and mips 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application, but cannot verify this, which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted system call.

Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c in the Linux kernel before 2.6.28-rc1 might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

Array index error in arch/mips/kernel/scall64-o32.S in the Linux kernel before 2.6.28-rc8 on 64-bit MIPS platforms allows local users to cause a denial of service (system crash) via an o32 syscall with a small syscall number, which leads to an attempted read operation outside the bounds of the syscall table.

The parisc_show_stack function in arch/parisc/kernel/traps.c in the Linux kernel before 2.6.28-rc7 on PA-RISC allows local users to cause a denial of service (system crash) via vectors associated with an attempt to unwind a stack that contains userspace addresses.

The inotify functionality in Linux kernel 2.6 before 2.6.28-rc5 might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount.

Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933.

The hfsplus_block_allocate function in fs/hfsplus/bitmap.c in the Linux kernel before 2.6.28-rc1 does not check a certain return value from the read_mapping_page function before calling kmap, which allows attackers to cause a denial of service (system crash) via a crafted hfsplus filesystem image.

Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.

Rule Set Based Access Control (RSBAC) before 1.3.5 does not properly use the Linux Kernel Crypto API for the Linux kernel 2.6.x, which allows context-dependent attackers to bypass authentication controls via unspecified vectors, possibly involving User Management password hashing and unchecked function return codes.

The dvd_read_bca function in the DVD handling code in drivers/cdrom/cdrom.c in Linux kernel 2.2.16, and later versions, assigns the wrong value to a length variable, which allows local users to execute arbitrary code via a crafted USB Storage device that triggers a buffer overflow.

artswrapper in aRts, when running setuid root on Linux 2.6.0 or later versions, does not check the return value of the setuid function call, which allows local users to gain root privileges by causing setuid to fail, which prevents artsd from dropping privileges.
