PT-2026-97389

Name of the Vulnerable Software and Affected Versions PgBouncer versions prior to 1.25.3 Description An integer overflow exists in the packet buffer growth logic. When processing sufficiently large input, the buffer size computation overflows, causing a growth loop that cannot terminate. Since th...

CVE-2026-82717: Heap-based Buffer Overflow

In NLnet Labs Unbound up to and including 1.26.0, a vulnerability was found in that can progressively corrupt heap memory and under certain systems and compilation options could lead to remote code execution. The vulnerability starts when CNAME synthesis during an upstream response needs to...

CVE-2026-74743

A flaw was found in the Linux kernel's macvlan component. The macvlan component incorrectly initializes network packet buffer skb headroom and tailroom values, failing to inherit them from the underlying network device. This can occur when the underlying device requires additional space for heade...

CVE-2026-72319

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. This vulnerability occurs when the system processes Internet Control Message Protocol ICMP errors originating from network tunnels. Specifically, after stripping outer packet headers, the IPVS component fails to ensure that...

kernel: rxrpc: Fix potential UAF after skb_unshare() failure

A flaw was found in the Linux kernel's rxrpc subsystem. This vulnerability arises when the system attempts to unshare a packet buffer, and the operation fails due to an allocation issue. This failure can lead to a Use-After-Free UAF condition, where the system attempts to access memory that has...

CVE-2026-52943

A flaw was found in the Linux kernel. The pskbcarveinsideheader and pskbcarveinsidenonlinear helper functions, which handle network packet buffers, do not correctly account for zero-copy references. This oversight can lead to a use-after-free vulnerability, where memory is prematurely released...

CVE-2026-45998

CVE-2026-48690

FastNetMon Community Edition through 1.2.9 contains an integer overflow vulnerability in the packet capture buffer allocation. In src/packetstorage.hpp, the allocatebuffer function computes memorysizeinbytes as 'buffersizeinpackets maxcapturedpacketsize + sizeoffastnetmonpcappkthdrt +...

CVE-2026-48684

FastNetMon Community Edition through 1.2.9 contains an out-of-bounds read in the NetFlow v9 options template parser. In processnetflowv9optionstemplate src/netflowplugin/netflowv9collector.cpp, the scope parsing loop lines 224-229 iterates until scopesoffset reaches the attacker-controlled...

CVE-2026-48690

CVE-2026-48690 affects FastNetMon Community Edition up to v1.2.9. The issue is an integer overflow in the packet capture buffer allocation: allocate_buffer() computes memory_size_in_bytes as buffer_size_in_packets * (max_captured_packet_size + sizeof(fastnetmon_pcap_pkthdr_t)) + sizeof(fastnetmon...

UBUNTU-CVE-2026-23122

In the Linux kernel, the following vulnerability has been resolved: igc: Reduce TSN TX packet buffer from 7KB to 5KB per queue The previous 7 KB per queue caused TX unit hangs under heavy timestamping load. Reducing to 5 KB avoids these hangs and matches the TSN recommendation in I225/I226 SW Use...
