CVE-2026-97989

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...

CVE-2026-98119

A null-pointer dereference vulnerability exists in the Linux kernel 's netfs component. When netfs_alloc_subrequest() fails during an unbuffered write, it returns a NULL subrequest. The system subsequently attempts to initialize members of this NULL pointer within netfs_prepare_write() , leading ...

In the Linux kernel, the following vulnerability has been resolved: netfs: break unbuffered write when netfsallocsubrequest fails syzbot reported a null-ptr-deref below 1 following a fault injection in netfsallocsubrequest. 0 When netfsallocsubrequest fails, subreq is NULL. Later, netfspreparewri...

In the Linux kernel, the following vulnerability has been resolved: ALSA: ump: do not touch legacyrmidi before it exists sndumpparseendpoint sets ump-parsed on every exit, including error, before the caller attaches the legacy rawmidi device. umphandleepnamemsg then treats parsed as "legacyrmidi ...

CVE-2026-98086

The Linux kernel contains a vulnerability in the ALSA subsystem related to the UMP component. The function snd_ump_parse_endpoint() incorrectly sets ump->parsed on every exit, including errors, before the legacy rawmidi device is attached. Consequently, ump_handle_ep_name_msg() may treat parse...

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. That is NULL for a base BTF - e.g. the vmlinux BTF that bpfsnprintfbtf renders against - since base BTF ...

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...

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...

CVE-2026-98063

The Linux kernel contains a NULL pointer dereference vulnerability in the btf_var_show() function. The issue occurs because btf_var_show() unconditionally calls btf_type_id_resolve() , which dereferences btf->resolved_ids . This pointer is NULL for base BTF structures, such as the vmlinux BTF ...

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...

EUVD-2026-86628

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-2026-97416

The Linux kernel contains a vulnerability in the btrfs filesystem. A null-pointer dereference can occur during the btrfs_balance operation if metadata corruption leaves a chunk in the chunk tree without a corresponding block group in the in-memory cache. Specifically, the function btrfs_may_alloc...
