Summary

The (1) hugetlb_vmtruncate_list and (2) hugetlb_vmtruncate functions in fs/hugetlbfs/inode.c in the Linux kernel before 2.6.19-rc4 perform certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE units, which allows local users to cause a denial of service (panic) via unspecified vectors.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
