kernel: netfilter: nft_payload: incorrect arithmetics when fetching VLAN header bits

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftpayload component. An incorrect arithmetic operation when processing VLAN Virtual Local Area Network header bits in double-tagged packets can lead to a heap-buffer-overflow. A local attacker could exploit this ...

[NetScaler] HA Full Sync may cause Heartbeats missing

In a NetScaler HA High Availability setup, you may observe the following issues: HA Full sync can cause both nodes report peer node DOWN due to heartbeats missing. A new command propagation can cause HA Full sync again, and also leads node DOWN. The issue happens when all of the following trigger...

kernel: Netfilter integer overflow vulnerability in nft_payload_copy_vlan

A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution...
