CVE-2026-98008

The Linux kernel contains a NULL pointer dereference vulnerability within the net: macb driver. When the device tree describes a fixed-link without an "mdio" child node, the macb_mii_init() function returns early without allocating the MDIO bus, leaving bp->mii_bus as NULL . This causes a kern...

CVE-2026-98006

The Linux kernel contains a use-after-free vulnerability in the ALSA caiaq USB device driver. The issue arises because the ep1_in_urb (and midi_out_urb) objects are embedded within the snd_usb_caiaqdev structure. When a command fails due to a timeout and snd_card_free() is called to release the c...

CVE-2026-98007

The Linux kernel contains a vulnerability in the bpf_loop() helper function where the nr_loops argument is incorrectly declared as ARG_ANYTHING. This allows privileged programs to pass pointer values instead of scalars. Because the verifier marks these registers as precise, passing a pointer trig...

CVE-2026-98005

The Linux kernel contains a vulnerability within the erofs file system regarding the encoding of inode_share cache keys . Previously, keys were encoded as fingerprint || domain_id, which created ambiguity as the fingerprint could be incorrectly parsed as part of a domain ID. The fix involves chan...

CVE-2026-98004

The Linux kernel addresses a vulnerability within the iommu/riscv component related to command queue publishing. The fix ensures that the software producer state only advances after a command is written and the hardware tail is updated. To prevent other CPUs from being blocked by a long poll when...

CVE-2026-98003

The Linux kernel contains a vulnerability in the iommu/amd component where GA log buffers are reallocated during every resume operation. The root cause is that the iommu_init_ga_log() function unconditionally assigns pointers to iommu->ga_log and iommu->ga_log_tail, causing a memory leak of...

CVE-2026-98002

The Linux kernel contains a vulnerability in the iommu/amd component due to an ineffective error check during nested domain allocation. The function amd_iommu_pdom_id_alloc() returns an int , which can be a negative errno (such as -ENOSPC) if the ID space is exhausted or memory is short. However,...

CVE-2026-98001

The Linux kernel contains a vulnerability in the hwmon (ltc4282) driver. The ltc428_clk_provider_setup() function fails to fully initialize all members of the clk_init_data structure, specifically leaving init.num_parents uninitialized. This oversight can lead to a system crash , particularly whe...

CVE-2026-98000

The Linux kernel contains a potential Use-After-Free (UAF) vulnerability in the hwmon subsystem specifically within the pec_store() function. The issue occurs because the code uses guard(mutex)(&hwdev->lock) to manage a mutex. If a chip write operation returns an error other than -EOPNOTSUPP, ...

CVE-2026-97998

A vulnerability exists in the Linux kernel 's netfilter: nfnetlink_log component where instances are refcounted, but memory release only occurs during a 1 -> 0 transition , while unlinking from hashes can happen at any refcount. Uncooperative userspace can trigger a race condition by forcing a...

CVE-2026-97997

The Linux kernel contains a vulnerability in the virtio_ring component where a failed packed add can leave stale AVAIL and USED bits in the descriptors. When vring_map_one_sg() fails mid-operation, unmap_release restores flags but leaves descriptors marked as available. This causes the device to ...

CVE-2026-97996

A use-after-free vulnerability exists in the Linux kernel within the unregister_virtio_device() function. The issue occurs because device_unregister() drops the last reference to the device, triggering a release callback that frees the memory containing the virtio_device struct for certain transp...

CVE-2026-97995

The Linux kernel contains a vulnerability in the virtio_console driver where the remove_vqs() function incorrectly passes leftover cookies to free_buf(). If a control message remains on c_ovq when a device is unbound, free_buf() treats these cookies as struct port_buffer and reads past the ports_...

CVE-2026-97993

A vulnerability exists in the Linux kernel 's vhost-vdpa driver within the vhost_vdpa_set_config_call() function. The issue arises because the code swaps the return value of eventfd_ctx_fdget() into v->config_ctx before checking for errors, briefly holding an ERR_PTR . If a config interrupt oc...

CVE-2026-97994

The Linux kernel contains a vulnerability in the vhost-vdpa component where vhost_vring_set_num() accepts a queue size that exceeds the device's maximum capacity without proper validation against get_vq_num_max(). A process with access to /dev/vhost-vdpa-* can exploit this to configure a queue la...

CVE-2026-97992

The Linux kernel contains a use-after-free vulnerability in the vhost-vdpa component. The issue occurs because vhost_vdpa_config_cb() accesses v->config_ctx without holding a lock or taking a reference, while VHOST_VDPA_SET_CONFIG_CALL replaces the field and immediately frees the old context v...

CVE-2026-97990

The Linux kernel is vulnerable in the vdpa_sim_net component due to an improper check of the vringh_iov_pull_iotlb() return value. Because the function returns a signed byte count, a failed TX pull results in a negative error that is incorrectly added to an unsigned byte counter. This value is th...

CVE-2026-97991

The Linux kernel contains a vulnerability in vdpa_sim_blk where the vdpasim_blk_check_range() function logs an invalid start sector but fails to halt validation. This allows an unsigned capacity subtraction to underflow, leading to an out-of-range buffer offset reaching the data path. The invalid...

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-2026-97988

The Linux kernel contains a vulnerability in vhost-net and vhost-vsock related to vring access during IOTLB transitions . When VIRTIO_F_ACCESS_PLATFORM changes, cached vring pointers and IOTLB metadata may be interpreted in the wrong address space, potentially leaving stale ring mappings in use. ...
