Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: vdpasimblk: The number of address spaces and virtqueue groups were set. The commit bda324fd037a “vdpasim: control virtqueue support” added two new fields nas, ngroups to vdpasimdevattr, but we forgot to initialize them for...
SUSE CVE-2026-43248
In the Linux kernel, the following vulnerability has been resolved: vhost: move vdpa group bound check to vhostvdpa 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 vdpasim where a valid ASID can be assign...
