PT-2026-61227

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the dma buf fd tracepoint. This occurs because a thread sharing the file descriptor table can call close after FD ADD returns but before DMA BUF TRACE...

CVE-2026-52950

A flaw was found in the Linux kernel, specifically within the drm/xe/dma-buf component. This Use-After-Free UAF vulnerability occurs due to an issue in a retry loop, where a buffer object is prematurely freed on error. An attacker could potentially exploit this to cause memory corruption, leading...

CVE-2026-52951

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-2026-52951

CVE-2026-52951 affects the Linux kernel, in the drm/xe/dma-buf subsystem, due to race conditions in the invalidate_mappings hook during BO (buffer object) handling. The issue arises when xe_bo_alloc() and an attach occur before xe_dma_buf_init_obj() completes, making the BO visible on the attachm...

In the Linux kernel, the following vulnerability has been resolved: media: videobuf2: Set vmaflags in vb2dmasgmmap vb2dmacontig sets VMA flags VMDONTEXPAND and VMDONTDUMP and I do not see a reason why vb2dmasg should behave differently. This avoids hitting WARNON!vma-vmflags & VMDONTEXPAND; in...

CVE-2026-46312

CVE-2026-46312 is a Linux kernel vulnerability involving media: videobuf2 where vb2_dma_sg_mmap did not set the VMA flags, potentially triggering a WARN_ON in drm_gem_mmap_obj() during mmap() of an imported dma-buf. The fix adds proper VMA flag handling in vb2_dma_sg_mmap_mmap (consistent with vb...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - drm/xe: Fix dma-buf attachment leak in xegemprimeimport When xedmabufinitobj fails, the attachment from dmabufdynamicattach is not detached. Add dmabufdetach...

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...
