CVE-2026-98064

The Linux kernel contains a NULL-pointer dereference vulnerability within the BPF subsystem. The issue occurs in btf_modifier_show() when it attempts to call the show() operation on a void type (type_id 0, BTF_KIND_UNKN). Because the kind_ops[] array lacks an entry for this type, the pointer is N...

CVE-2026-97989

The Linux kernel contains a vulnerability in vduse where vduse_validate_config() fails to properly validate the vq_align parameter, checking only the upper bound. This allows invalid values to reach vring_create_virtqueue_map(). Specifically, because split-ring helpers use align - 1 as a bit mask...

CVE-2026-97989 vduse: validate virtqueue alignment

In the Linux kernel, the following vulnerability has been resolved: vduse: validate virtqueue alignment vdusevalidateconfig only checks the upper bound of vqalign. Invalid values can therefore reach vringcreatevirtqueuemap. The split-ring helpers use align - 1 as a bit mask, so the alignment must...

In the Linux kernel, the following vulnerability has been resolved: ipv6: null-check fib6node before accessing in ip6delrtsiblings syzbot reported a null-ptr-deref in ip6delrtsiblings 0. The stack trace hinted towards a null dereference of rt-fib6node when fn-leaf is accessed in ip6delrtsiblings...

CVE-2026-97974

The Linux kernel contains a null-pointer dereference vulnerability within the ipv6 networking stack, specifically in the __ip6_del_rt_siblings() function. The issue occurs because rt->fib6_node can be set to NULL by a concurrent thread (e.g., when replacing an ECMP route via RTM_NEWROUTE with ...

CVE-2026-98063

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL-ptr-deref in btfvarshow btfvarshow calls btftypeidresolve unconditionally, which dereferences btf-resolvedids.

CVE-2026-98064

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL-ptr-deref when showing a void BTF type btfmodifiershow resolves the modifier and then calls btftypeopst-show unconditionally. For the void type typeid 0, BTFKINDUNKN kindops has no entry, so -show is NULL. A "const...
