CVE-2026-93212

A vulnerability exists in the Linux kernel nfsd service where a NULL pointer dereference occurs in nfsd_file_net_dispose(). During per-net teardown, nn->nfsd_serv is cleared before the filecache laundrette is shut down. This allows the service thread to execute a dispose pass that identifies e...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: SCTP: Stream: Fully roll back denied add-stream states When the request to add a stream ADDOUTSTREAMS is denied, SCTP only reduces the size of the queued chunks and lowers the outcnt value. This leaves the removed stream’s metada...
