CVE-2026-52951 drm/xe/dma-buf: handle empty bo and UAF races

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: handle empty bo and UAF races There look to be some nasty races here when triggering the invalidatemappings hook: 1 We do xeboalloc followed by the attach, before the actual full bo init step in xedmabufinitobj...

CVE-2026-52950 drm/xe/dma-buf: fix UAF with retry loop

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init d...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Fixed a potential UAF in xeoaaddconfigioctl In xeoaaddconfigioctl, we accessed oaconfig-id after dropping metricslock. Since this lock protects the lifetime of oaconfig, an attacker could guess the id and call...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Set numsyncs to a limit to prevent overly large allocations. The exec and vmBind ioctls allow userspace to specify an arbitrary value for numsyncs. Without bounds checking, a very large value of numsyncs can result in an...

CVE-2026-46201

A flaw was found in the Linux kernel's drm/xe subsystem. When handling dma-buf attachments, a resource leak occurs if the initialization of a dma-buf object fails, as the attachment is not properly detached. This oversight can lead to resource exhaustion, potentially allowing a local attacker to...
