Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the mm/vmalloc component of the Linux kernel, where the
vmap pages range noflush() function assumes that its argument pages** contains pages with the same page shift. However, if gfp flags includes GFP NOFAIL with high order in vm area alloc pages() and page allocation fails for high order, pages** may contain two different page shifts (high order and order-0), leading to incorrect mappings and potentially resulting in memory corruption. Users might encounter this issue when using kvmalloc() with GFP NOFAIL and GFP X flags, and vmap allow huge is set to true.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
