CVE-2026-89790

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition can occur during IPv6 multipath route rebalancing, where a concurrent update can lead to a divide-by-zero error. This vulnerability can cause the kernel to crash, resulting in a Denial of Service DoS for the affect...

CVE-2026-93226

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition occurs when reading route exception lists without proper synchronization against concurrent route updates. A local user can trigger this flaw by querying network routing tables during simultaneous route updates,...

CVE-2026-98598

A flaw was found in the Linux kernel's IPv6 networking subsystem. A local attacker or network traffic triggering route exceptions while an IPv6 route is being removed can cause a circular reference leak. This failure to release resources prevents network devices from unregistering, resulting in...

CVE-2026-98595

A flaw was found in the Linux kernel's UDP networking subsystem. When a connected User Datagram Protocol UDP socket bound to a specific address is disconnected, the kernel fails to remove the socket entry from its internal connection lookup table. A local user can cause stale entries to persist,...

CVE-2026-98573

A flaw was found in the Linux kernel. An integer underflow in the networking subsystem allows an attacker to trigger an out-of-bounds memory copy by sending specially crafted Internet Protocol version 6 IPv6 packets with extension headers. This vulnerability can lead to kernel memory corruption,...

CVE-2026-98558
