High severity7.8NVD Advisory· Published May 6, 2026· Updated Jun 17, 2026
CVE-2026-43248
CVE-2026-43248
Description
In the Linux kernel, the following vulnerability has been resolved:
vhost: move vdpa group bound check to vhost_vdpa
Remove duplication by consolidating these here. This reduces the posibility of a parent driver missing them.
While we're at it, fix a bug in vdpa_sim where a valid ASID can be assigned to a group equal to ngroups, causing an out of bound write.
