CVE-2026-53372
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Block PASID attachment to nested domain with dirty tracking Kernel lacks dirty tracking support on nested domain attached to PASID, fails the attachment early if nesting parent domain is dirty tracking configured, otherwise dirty pages would be lost.
CVE-2026-53371
In the Linux kernel, the following vulnerability has been resolved: RDMA/ionic: bound node_desc sysfs read with %.64s node_desc[64] in struct ib_device is not guaranteed to be NUL- terminated. The core IB sysfs handler uses "%.64s" for exactly this reason (drivers/infiniband/core/sysfs.c:1307), since node_desc_store() performs a raw memcpy of up to IB_DEVICE_NODE_DESC_MAX bytes with no NUL termination: memcpy(desc.node_desc, buf, min_t(int, count, IB_DEVICE_NODE_DESC_MAX)); If exactly 64 bytes are written via the node_desc sysfs file, the array contains no NUL byte. The ionic hca_type_show() handler uses unbounded "%s" and will read past the end of node_desc into adjacent fields of struct ib_device until it encounters a NUL. ionic supports IB_DEVICE_MODIFY_NODE_DESC, so this is triggerable by userspace. Match the core handler and bound the format specifier.
CVE-2026-53370
In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel: Improve validation and configuration of ACR masks Currently there are several issues on the user space ACR mask validation and configuration. - The validation for user space ACR mask (attr.config2) is incomplete, e.g., the ACR mask could include the index which belongs to another ACR events group, but it's not validated. - An early return on an invalid ACR mask caused all subsequent ACR groups to be skipped. - The stale hardware ACR mask (hw.config1) is not cleared before setting new hardware ACR mask. The following changes address all of the above issues. - Figure out the event index group of an ACR group. Any bits in the user-space mask not present in the index group are now dropped. - Instead of an early return on invalid bits, drop only the invalid portions and continue iterating through all ACR events to ensure full configuration. - Explicitly clear the stale hardware ACR mask for each event prior to writing the new configuration. Besides, a non-leader event member of ACR group could be disabled in theory. This could cause bit-shifting errors in the acr_mask of remaining group members. But since ACR sampling requires all events to be active, this should not be a big concern in real use case. Add a "FIXME" comment to notice this risk.
