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.
AnalysisAI
Out-of-bounds write in Linux kernel vhost_vdpa subsystem allows local authenticated users to achieve arbitrary kernel memory corruption via ASID group assignment. Affects Linux kernel versions 5.19 through 6.19.x, with vendor patches available for stable branches 6.12.75, 6.18.16, 6.19.6, and mainline 7.0. …

RemediationAI
Within 24 hours: Inventory all systems running Linux kernel versions 5.19-6.19.x and identify those exposed to local authenticated user access. Within 7 days: Apply vendor patches to stable branches (6.12.75, 6.18.16, 6.19.6) or mainline kernel 7.0 on non-critical systems; prioritize systems with broad local user access. …
