Description OSIDB Bzimport 2026-08-15 06:35:33 UTC 
In the Linux kernel, the following vulnerability has been resolved:

vmalloc: fix NULL pointer dereference in is_vm_area_hugepages()

find_vm_area() can return NULL if the given address is not a valid vmalloc
area.  Check the return value before dereferencing it to avoid a kernel
crash.
