CVE-2026-99025

A vulnerability in the Linux kernel 's openvswitch component causes a soft lockup and system panic during a netlink flow dump . The issue occurs because ovs_flow_cmd_dump() calls ovs_flow_stats_get(), which uses spin_unlock_bh(). This repeatedly enables local softirqs, causing the dumping thread ...

CVE-2026-98644

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local user could cause a Denial of Service DoS by executing batch lookup or deletion operations on large hash maps. Due to a missing rescheduling check when traversing consecutive empty hash table entries, the kernel c...

CVE-2026-80866

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication subsystem. A busy-wait loop in the tipcexitnet function, intended to wait for UDP bearer cleanup, can consume excessive CPU cycles. This issue arises when the condresched function is ineffective, such as when a...

CVE-2026-98494

A flaw was found in the Linux kernel's atl1 network driver. During a PCIe link or hardware reset, the network adapter can return an out-of-range status value that the driver fails to validate properly. This condition can trap the driver in an infinite loop, resulting in a kernel soft lockup and...

CVE-2026-98488

A flaw was found in the Linux kernel's Atheros L1E Gigabit Ethernet atl1e network driver. While the network interface hardware is resetting, it can report an unexpected out-of-range status value during transmit packet processing. Because the driver does not properly validate this value, it enters...
