CVE-2026-98123

The Linux kernel is vulnerable to a remote denial of service (DoS) and an out-of-bounds read due to how SCTP handles ASCONF-ACK parameters. The sctp_verify_asconf() function uses padding during parameter iteration, while the consumer sctp_get_asconf_response() iterates using raw lengths. An odd-l...

CVE-2026-98106

The Linux kernel contains a vulnerability where a device-private folio migrated to system memory by a CPU fault remains reachable through the raw-PFN eviction path until migration finalization. If the same folio is selected for eviction during this window, a second migration attempt occurs, leavi...

CVE-2026-98056 nvme: remove stale namespaces by NSID range during scan

In the Linux kernel, the following vulnerability has been resolved: nvme: remove stale namespaces by NSID range during scan nvmescannslist drops the stale namespaces in each gap in the reported NSID list one NSID at a time. Every iteration calls nvmefindgetns to look the namespace up and removes ...

CVE-2026-98056

The Linux kernel contains a vulnerability in the nvme driver where the nvme_scan_ns_list() function inefficiently processes stale namespaces. Specifically, it drops stale namespaces in gaps by iterating through every individual NSID one at a time. Because NSIDs are 32-bit, a sparse NSID space can...
