CVE-2008-3534: Canonical Ubuntu Linux

Medium severity, CVSS 4.9. EPSS: 0.5% chance of exploitation in the next 30 days.

The shmem_delete_inode function in mm/shmem.c in the tmpfs implementation in the Linux kernel before 2.6.26.1 allows local users to cause a denial of service (system crash) via a certain sequence of file create, remove, and overwrite operations, as demonstrated by the insserv program, related to allocation of "useless pages" and improper maintenance of the i_blocks count.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 7.10 only; version 8.04 only
• Debian Debian Linux: version 4.0 only
• Linux Linux Kernel: before 2.6.26.1 (fixed in 2.6.26.1)
