Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkqueue: The hash table is now created per queue. Sharing a global hash table among all queues is tempting, but it can lead to crashes. Bug: KASAN: A “slab-use-after-free” issue exists in...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: igc: The TX packet buffer size per queue has been reduced from 7KB to 5KB. The previous setting of 7KB per queue caused issues with the TX unit during heavy timestamping operations. Reducing the buffer size to 5KB avoids such...

CVE-2026-43084

CVE-2026-43084 affects the Linux kernel netfilter nfnetlink_queue. The vulnerability stems from sharing a global hash table across all queues, allowing a parallel CPU to access a nf_queue_entry after it has been freed, causing a slab-use-after-free (KASAN) and potential crash/DoS. The fix is to m...
