CVE-2026-46224

A flaw was found in the Linux kernel's drm/xe driver. When a buffer object allocation fails within the xedmabufinitobj function, a pre-allocated storage buffer is not correctly released. This oversight can lead to a resource leak, potentially causing system instability or a denial of service DoS...

CVE-2026-46201

CVE-2026-46201 affects the Linux kernel drm/xe: an error path in xe_gem_prime_import() leaks a dma_buf attachment when xe_dma_buf_init_obj() fails, because the attachment from dma_buf_dynamic_attach() is not detached. The fix explicitly detaches via dma_buf_detach() before returning an error, avo...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the drm/xe component when the xe gem prime import function is called. Specifically, if the xe dma buf init obj function fails, the attachment created by dma buf...

CVE-2026-46007

In the Linux kernel, the following vulnerability has been resolved: hwmon: powerz Avoid cacheline sharing for DMA buffer Depending on the architecture the transfer buffer may share a cacheline with the following mutex. As the buffer may be used for DMA, that is problematic. Use the high-level DMA...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...
