EUVD-2026-95537

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject dev-bound-only programs on other devices bpfoffloaddevmatch falls back to comparing offdev pointers after an exact netdev mismatch. Bound-only programs normally have NULL offdevs, so unrelated netdevs compare equal. A...

EUVD-2026-95535

In the Linux kernel, the following vulnerability has been resolved: net/sched: reject IDR error pointers when deleting actions tcfactiondelete drops the reference held by its lookup before calling tcfidrdeleteindex with the saved action index. An unlocked classifier can remove that action and...

CVE-2026-98380

In the Linux kernel, the following vulnerability has been resolved: net/sched: reject IDR error pointers when deleting actions tcfactiondelete drops the reference held by its lookup before calling tcfidrdeleteindex with the saved action index. An unlocked classifier can remove that action and...

CVE-2026-98380

A vulnerability exists in the Linux kernel 's net/sched component where tcf_idr_delete_index() fails to properly handle IDR error pointers . Specifically, if an unlocked classifier removes an action and reserves the same IDR slot with ERR_PTR(-EBUSY) between the lookup and deletion, the system tr...

CVE-2026-98379

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6trpfilter: reject routes without inet6dev ip6routelookup can return an error-free route whose rt6iidev is NULL. Lowering an external nexthop device's MTU below IPV6MINMTU tears down its inet6dev while fib6ifdown...

CVE-2026-98379

The Linux kernel contains a vulnerability in the netfilter: ip6t_rpfilter component. The ip6_route_lookup() function can return a route where rt6i_idev is NULL if an external nexthop device's MTU is lowered below IPV6_MIN_MTU, causing the inet6_dev to be torn down while the route remains in the F...

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6trpfilter: reject routes without inet6dev ip6routelookup can return an error-free route whose rt6iidev is NULL. Lowering an external nexthop device's MTU below IPV6MINMTU tears down its inet6dev while fib6ifdown...

CVE-2026-98378

In the Linux kernel, the following vulnerability has been resolved: bpf: Skip unsettled links in link iterator bpflinkprime inserts a link into linkidr before anoninodegetfile succeeds and before bpflinksettle publishes the ID in link-id. bpflinkbyid treats such an ID-zero link as unsettled, but...

EUVD-2026-95533

In the Linux kernel, the following vulnerability has been resolved: bpf: Skip unsettled links in link iterator bpflinkprime inserts a link into linkidr before anoninodegetfile succeeds and before bpflinksettle publishes the ID in link-id. bpflinkbyid treats such an ID-zero link as unsettled, but...

CVE-2026-98378

The Linux kernel contains a vulnerability in the bpf subsystem where the link iterator fails to skip unsettled links. Specifically, bpf_link_prime() inserts a link into link_idr before bpf_link_settle() publishes its ID. While bpf_link_by_id() correctly treats ID-zero links as unsettled, the link...

CVE-2026-98376

The Linux kernel contains a vulnerability in the eBPF subsystem where percpu_array_map_ops.map_meta_equal incorrectly points to bpf_map_meta_equal(). Because the latter fails to compare max_entries, a percpu array used as an inner map can be replaced with a smaller one, bypassing size checks. Thi...

CVE-2026-98376

In the Linux kernel, the following vulnerability has been resolved: bpf: Use arraymapmetaequal for percpu array inner map replacement percpuarraymapops.mapmetaequal points to the generic bpfmapmetaequal, which does not compare maxentries. When a percpu array serves as an inner map, replacing it...

CVE-2026-98377

In the Linux kernel, the following vulnerability has been resolved: vlan: require the MAC header to be present in vlaninsertinnertag vlaninsertinnertag only guarantees head room via skbcowhead, never that maclen bytes of MAC header are present. Its ETHHLEN wrappers - vlaninserttag under...

EUVD-2026-95531

In the Linux kernel, the following vulnerability has been resolved: bpf: Use arraymapmetaequal for percpu array inner map replacement percpuarraymapops.mapmetaequal points to the generic bpfmapmetaequal, which does not compare maxentries. When a percpu array serves as an inner map, replacing it...

CVE-2026-98377

The Linux kernel contains a vulnerability in the vlan component where the __vlan_insert_inner_tag() helper function fails to verify the presence of a MAC header before rewriting the first 16 bytes. Specifically, on IFF_TUN devices with hard_header_len == 0, the system may accept a one-byte AF_PAC...

CVE-2026-98289

A flaw was found in the Linux kernel's UNIX domain socket afunix subsystem. A logic error in the socket garbage collection algorithm can prevent cyclical socket references from being properly identified and reclaimed. A local user could exploit this flaw to cause a resource leak, potentially...

CVE-2026-98239

A flaw was found in the Linux kernel's LAN743x network device driver. This vulnerability allows an attacker capable of transmitting network traffic to an affected system to cause a Denial of Service DoS or memory corruption. The issue occurs because the driver attempts to update checksum...
