CVE-2026-53143

CVE-2026-53143 affects the Linux kernel DRM/amdkfd path for SDMA queues on GFX11. The v11 MQD manager incorrectly reused the 2048-byte v11_compute_mqd path for SDMA queues, causing a 1536-byte overflow when checkpointing and restoring MQDs (CRIU context). This led to leaking adjacent GTT memory d...

CVE-2026-53143

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix buffer overflow in SDMA queue checkpoint/restore on GFX11 The v11 MQD manager incorrectly assigned the CP-compute variants of checkpointmqd/restoremqd for KFDMQDTYPESDMA queues. These functions use sizeofstruct...

CVE-2026-52923

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

UBUNTU-CVE-2026-52923

In the Linux kernel, the following vulnerability has been resolved: ipc: limit nextid allocation to the valid ID range The checkpoint/restore sysctl path can request the next SysV IPC id through ids-nextid. ipcidralloc currently forwards that request to idralloc with an open-ended upper bound. If...

CVE-2026-52923

CVE-2026-52923 concerns the Linux kernel and a bug in the checkpoint/restore path related to SysV IPC id allocation. The issue occurs when ids->next_id is passed to idr_alloc() with an open-ended upper bound, allowing the valid tail of the IPC id space to spill past ipc_mni. The result can be ...

GHSA-33VJ-92QQ-66HC containerd CRI checkpoint restore CDI annotation smuggling

Impact containerd's CRI implementation improperly trusts Container Device Interface CDI annotations found within untrusted checkpoint image metadata during container restoration. When restoring a container from a checkpoint, containerd preserves CDI-related annotations from the checkpoint archive...

UNIX Symbolic Link (Symlink) Following

Overview Affected versions of this package are vulnerable to UNIX Symbolic Link Symlink Following in the CRI checkpoint restore plugin due to improper validation of symlinked paths. An attacker can access arbitrary files on the host by crafting a malicious checkpoint image and leveraging the...

GHSA-RGH6-RFWX-V388 Arbitrary host CRI log file read via symlink following in CRI checkpoint restore

Impact A bug was found in containerd where the CRI plugin restores container.log from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via kubectl logs. Patches This bug has been fixed in the following containerd versions: 2.3.2...

cri-o: Checkpoint restore can be triggered from different namespaces

A vulnerability was found in CRI-O, where it can be requested to take a checkpoint archive of a container and later be asked to restore it. When it does that restoration, it attempts to restore the mounts from the restore archive instead of the pod request. As a result, the validations run on the...
