CVE-2010-0727
CVE-2010-0727 affects the Linux kernel: the gfs2_lock (and on RHEL 5/6 gfs_lock) fails to properly remove POSIX locks on files that are setgid without group-execute permission. This allows a local attacker to trigger a denial of service or system crash by locking a file on a GFS or GFS2 filesyste...

The Difficulty of Un-Authentication
By Bruce Schneier In computer security, a lot of effort is spent on the authentication problem. Whether it’s passwords, secure tokens, secret questions, image mnemonics, or something else, engineers are continually coming up with more complicated — and hopefully more secure — ways for you to prov...

kernel: add rcu_read_lock() to fcheck() in both dnotify, locks.c and fix fcntl store/load race in locks.c
Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to 1 execute code in parallel or 2 exploit a race condition to obtain "re-ordered access to the descriptor table."...

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