CVE-2008-3534

CVE-2008-3534 affects the Linux kernel tmpfs implementation (shmem.c: shmem_delete_inode). A local attacker could crash the system by a specific sequence of file create/remove/overwrite operations, linked to allocation of “useless pages” and improper maintenance of i_blocks. Public advisories con...
