CVE-2008-4307 describes a race condition in the Linux kernel's NFS file locking mechanism (do_setlk function in fs/nfs/file.c) affecting versions prior to 2.6.26. This flaw allows a local attacker to trigger a denial of service (system crash) by exploiting a race between fcntl and close operations during an interrupted RPC call, leading to a stray POSIX lock. The vulnerability has a CVSS score of 4.0, indicating low attack complexity and requiring local access, with the primary impact being system availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
