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-2026-48684

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...
