CVE-2026-98850

A flaw was found in the Linux kernel's packet socket implementation. An integer overflow occurs in the transmission ring buffer when calculating the total byte count of transmitted frames during a send operation. A local user with raw network privileges can exploit this issue to trigger an intern...

CVE-2026-31431-cleaned

copyFail.py — CVE Exploit Analysis Report Summary copyFail.py is a proof-of-concept PoC exploit that demonstrates a local privilege escalation vulnerability in the Linux kernel. By abusing the splice system call in combination with crafted socket options, the exploit gains the ability to corrupt...

CVE-2026-98503

A flaw was found in the Linux kernel's packet socket implementation. A local user can cause a Denial of Service DoS or system instability by triggering premature reuse of transmit ring buffer slots while packet data is still in flight. Because these shared memory slots may be released and reused...

PT-2026-117021

In the Linux kernel, the following vulnerability has been resolved: seg6: ensure packet data is writable before modifying SRH and IPv6 DA advance nextseg modifies the SRH Segments Left field and the IPv6 destination address without ensuring the packet data is writable. seg6 next csid advance arg...

CVE-2026-98233

A flaw was found in the Linux kernel's packet socket implementation. An attacker could cause a Denial of Service DoS by transmitting network packets that fail virtual network header processing. When processing encounters an error, the kernel fails to clear the ownership status of the assigned...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: fixed information leakage in /proc/net/ptype In one net namespace, after creating a packet socket without binding it to a device, users in other net namespaces can observe the newly added packettype by reading the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The can: hi311x module has corrected the ndochangemtu function to prevent buffer overflows. Sending a PFPACKET allows bypassing the CAN driver’s logic and directly reaching the xmit function of the CAN driver. The only check...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: etases58x: It is necessary to populate ndochangemtu to prevent buffer overflows.

CVE-2026-80906

In the Linux kernel, the following vulnerability has been resolved: net: packet: fix wrong transportheader when sending VLAN-tagged frame In packetparseheaders, when processing a VLAN-tagged frame, skbsetnetworkheader is called to advance networkheader past the VLAN tag to the inner protocol...

CVE-2026-80906

CVE-2026-80906 affects the Linux kernel net: packet subsystem. In packet_parse_headers(), when handling a VLAN-tagged frame, skb_set_network_header() advances the network header past the VLAN tag before skb_probe_transport_header() is called. This leaves skb->protocol set to the outer VLAN Eth...
