Detection-and-Mitigation-for-CVE-2022-2639 Description The Open vSwitch kernel module allows flexible userspace control over flow-level packet processing on selected network devices. It can be used to implement a plain Ethernet switch, network device bonding, VLAN processing, network access...

CVE-2026-97612

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS networking subsystem. When all labels are removed from an encapsulated packet, the kernel fails to clear internal protocol tracking metadata, leaving stale network header references. An attacker could exploit this flaw by...

CVE-2026-97611

A flaw was found in the Linux kernel's Open vSwitch subsystem. A race condition during the reallocation of internal flow table structures allows memory to be freed while it is still being accessed by packet processing routines, causing a use-after-free condition. An attacker can exploit this flaw...

CVE-2026-97612

The Linux kernel is vulnerable to a memory corruption issue in the MPLS stack. The skb_mpls_push() function records a pre-encapsulation network header but skb_mpls_pop() fails to clear it when the last label is popped. This allows Open vSwitch to re-push MPLS onto a packet where the inner_network...
