CVE-2026-43248

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the vhost component where the vdpa group bound check was duplicated, increasing the risk of a parent driver omitting the check. Additionally, a bug in vdpa sim allows a valid ASID (Address Space Identifier) to be assigned to a group equal to ngroups, which can lead to an out-of-bounds write.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
