CVE-2026-12659 Rockwell Automation Flex 5000® Adapter - Denial of Service

A denial-of-service security issue exists in the affected products. The security issue stems from improper handling of exceptional conditions when processing crafted CIP packets sent to the adapter. A power cycle is required to recover the module and associated I/O...

kernel: Linux kernel: Memory leak in networking due to incorrect GRO packet handling

A flaw was found in the Linux kernel's networking component. Incorrect memory accounting when handling Generic Receive Offload GRO packets can lead to a persistent memory leak. This occurs because the system incorrectly tracks memory usage for network packets, preventing proper cleanup of network...

CVE-2026-56413

Storage Concentrator SC & SCVM contains a command injection vulnerability in the msservice.pl service, which listens on TCP port 9000 by default and accepts custom network packets to perform device actions. An unauthenticated remote attacker can send a specially crafted packet containing a...

CVE-2026-12760

The CVE-2026-12760 vulnerability affects TP-Link Tapo C200 (v3) in the network packet handling path. It arises from improper handling of IPv4 fragmented packets, allowing an unauthenticated adjacent attacker to send crafted fragments to cause excessive resource usage, leading to a temporary DoS c...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ovpn: fixed a possible use-after-free in ovpnnetxmit. When constructing the skblist in ovpnnetxmit, skbsharecheck will free the original skb if it is shared. The current implementation continues to use the stale skb pointer fo...
