SUSE CVE-2026-72138
In the Linux kernel, the following vulnerability has been resolved: xen/gntdev: fix error handling in ioctl When gntdevioctlmapgrantref fails to copy the operation result back to userspace after successfully adding the mapping to the list, the error path returns -EFAULT without releasing the...
CVE-2026-72138
A flaw was found in the xen/gntdev component of the Linux kernel. When the gntdevioctlmapgrantref function fails to copy operation results back to userspace, it does not properly release a memory reference. This oversight can lead to a memory leak and a corrupted list entry. A local attacker coul...

CVE-2026-72138
The CVE describes a Linux kernel issue in xen/gntdev where gntdev_ioctl_map_grant_ref() could leak memory if copy_to_user() failed after adding a mapping and not releasing the acquired reference. The root cause involves mismanaged error paths: on failure to copy operation results back to userspac...

The vulnerability of the dmabufexp_from_pages() function in the drivers/xen/gntdev-dmabuf.c driver code of the Linux kernel’s page buffer device driver allows a attacker to cause a service failure.
The vulnerability of the dmabufexpfrompages function in the drivers/xen/gntdev-dmabuf.c driver for Linux kernel-based device buffer devices is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to cause a service failure...
