Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm/slab/kvfreercu: The switch to WQMEMRECLAIM wq was implemented. Currently, the kvfreercu APIs use a system workqueue, which is “systemunboundwq” for the driver’s RCU machinery to reclaim memory. Recently, the following kernel...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: nfsd: returns -EINVAL when namelen is 0 When we have a corrupted main.sqlite file in /var/lib/nfs/nfsdcld/, it may result in namelen being 0, which will cause memdupuser to return ZEROSIZEPTR. When we access the name.data that ha...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/sgx: Prevents attempts to reclaim poisoned pages TL;DR: In SGX, when pages are reclaimed, their contents are copied to secondary storage. SGX instructions do not properly handle machine checks. Nevertheless, existing SGX code...

SUSE CVE-2026-46265

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix WQMEMRECLAIM warning When sunrpc is used, if a reset triggered, our wq may lead the following trace: workqueue: WQMEMRECLAIM xprtiod:xprtrdmaconnectworker rpcrdma is flushing !WQMEMRECLAIM...

CVE-2026-46256

A flaw was found in the Linux kernel, specifically within the NFS Network File System LOCALIO optimization. This vulnerability allows for a recursion deadlock to occur during direct reclaim operations. When LOCALIO attempts to write pages back into NFS via nfswritepages, it can lead to a system...

CVE-2026-46265

A flaw was found in the Linux kernel's RDMA/hns component. When the sunrpc Sun Remote Procedure Call is in use and a reset is triggered, a workqueue dependency issue can occur during Queue Pair QP destruction. This can lead to a kernel warning related to memory reclaim, potentially causing system...
