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: TCP – fix for extracting packets from the stream When processing TCP stream data in ovpntcprecv, we receive large cloned skbs from strprcv, which may contain multiple coalesced packets. The current implementation has two...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mctp i3c: handling of NULL header addresses daddr can be NULL if there is no neighbour table entry present; in that case, the TX packet should be discarded. saddr is usually set by the MCTP core, but NULL values are also...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Firewire: In the net subsystem, a bug related to use-after-free was fixed in the fwnetfinishincomingpacket function. The netifrx function frees the skb, but we cannot dereference it to save the skb-len...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Only drop the call reference if one was actually acquired. The function rxrpcinputpacketonconn can process a packet for the client after the current client call on the channel has already been terminated. In this case,...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: scsi: qla2xxx: Fixed a crash that occurred during module load/unload tests. During purex packet handling, the driver incorrectly freed a pre-allocated structure. This issue was fixed by skipping that specific entry in the code...

CVE-2026-45998

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix potential UAF after skbunshare failure If skbunshare fails to unshare a packet due to allocation failure in rxrpcinputpacket, the skb pointer in the parent rxrpciothread will be NULL'd out. This will likely cause the...

CVE-2026-46000

CVE-2026-46000 in the Linux kernel: rxrpc vulnerability where security checks decrypt bits of a packet in place while the skb may be shared with a packet sniffer, potentially exposing a decrypted (apparently corrupted) packet. The fix: when a packet was cloned, the kernel now hands a copy of the ...

CVE-2026-46000

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix conn-level packet handling to unshare RESPONSE packets The security operations that verify the RESPONSE packets decrypt bits of it in place - however, the skbuff may be shared with a packet sniffer, which would lead to...
