Fedora 42: libpcap Medium Memory Corruption CVE-2025-11961 Advisory

New version 1.10.6. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-1e3425e7ea 2026-01-21 01:30:15.162774+00:00 -------------------------------------------------------------------------------- Name : libpcap Product : Fedora 42 Version : 1.10.6 Release : 1.fc42 URL : https://www.tcpdump.org/ Summary : A system-independent interface for user-level packet capture Description : Libpcap provides a portable framework for low-level network monitoring. Libpcap can provide network statistics collection, security monitoring and network debugging. Since almost every system vendor provides a different interface for packet capture, the libpcap authors created this system-independent API to ease in porting and to alleviate the need for several system-dependent packet capture modules in each application. Install libpcap if you need to do low-level network traffic monitoring on your network. -------------------------------------------------------------------------------- Update Information: New version 1.10.6 -------------------------------------------------------------------------------- ChangeLog: * Mon Jan 5 2026 Michal Ruprich - 14:1.10.6-1 - New version 1.10.6 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2426393 - libpcap-1.10.6 is available https://bugzilla.redhat.com/show_bug.cgi?id=2426393 [ 2 ] Bug #2426630 - CVE-2025-11961 libpcap: libpcap: Memory corruption via malformed MAC-48 address input [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2426630 [ 3 ] Bug #2426631 - CVE-2025-11961 libpcap: libpcap: Memory corruption via malformed MAC-48 address input [fedora-43] https://bugzilla.redhat.com/show_bug.cgi?id=2426631 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
