CVE-2025-39740

In the Linux kernel, the following vulnerability has been resolved: drm/xe/migrate: prevent potential UAF If we hit the error path, the previous fence if there is one has already been put prior to this, so doing a fencewait could lead to UAF. Tweak the flow to do to the put until after we do the...

CVE-2025-39740

The CVE-2025-39740 entry concerns a Linux kernel vulnerability in the DRM XE migration path. It describes a potential use-after-free (UAF) scenario if a fence_wait is performed after the previous fence has already been put(), on the error path. The fix changes the control flow so that the put() i...

PT-2025-37199

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The Linux kernel contains a use-after-free UAF issue within the drm/xe/migrate component. Specifically, a flaw exists where a fence object could be freed prematurely, leading to a...

CVE-2025-39698

In the Linux kernel, the following vulnerability has been resolved: iouring/futex: ensure iofutexwait cleans up properly on failure The iofutexdata is allocated upfront and assigned to the iokiocb asyncdata field, but the request isn't marked with REQFASYNCDATA at that point. Those two should...

CVE-2025-39698

CVE-2025-39698 concerns the Linux kernel io_uring/futex cleanup: io_futex_data is allocated upfront and wired into io_kiocb.async_data, but the request flag REQ_F_ASYNC_DATA may not be set at that time. On failure, the futex handler frees the data but may not clear async_data, so the data and fla...

kernel: mmc: sdio: fix possible resource leaks in some error paths

In the Linux kernel, the following vulnerability has been resolved: mmc: sdio: fix possible resource leaks in some error paths If sdioaddfunc or sdioinitfunc fails, sdioremovefunc can not release the resources, because the sdio function is not presented in these two cases, it won't call ofnodeput...

kernel: media: uvcvideo: Fix double free in error path

In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Fix double free in error path If the uvcstatusinit function fails to allocate the inturb, it will free the dev-status pointer but doesn't reset the pointer to NULL. This results in the kfree call in...
