Last modified

CVE-2009-3726 is a vulnerability of currently unknown severity. The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.. EPSS estimates a 12.00% chance of exploitation in the next 30 days.
