EUVD-2026-86664

In the Linux kernel, the following vulnerability has been resolved: net/sched: hhf: clamp quantum in change and init paths hhfchange accepts any quantum from userspace, including 1. With a crafted size table qdiscpktlen reaches 2 GiB, so quantum=1 makes the deficit-refill loop spin 2^31 times und...

CVE-2026-98012

The Linux kernel contains a vulnerability in the net/sched: sfq component where the sfq_change() function fails to properly restrict the quantum value. By providing a crafted size table causing qdisc_pkt_len to reach approximately 2 GiB, an attacker can set quantum=1 to trigger a deficit-refill l...

EUVD-2026-86665

In the Linux kernel, the following vulnerability has been resolved: net/sched: sfq: clamp quantum in change path sfqchange accepts any non-negative quantum only rejects intctl-quantum 120 with -EINVAL, matching fqcodelchange and the init clamp. Conditions to recreate the bug: CONFIGNETSCHSFQ=y...

EUVD-2026-86662

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: clamp quantum in parse and fallback paths etsqdiscchange falls back to pschedmtu with no floor for bands without an explicit quantum. With a crafted size table qdiscpktlen reaches 2 GiB, so a zero pschedmtu on a...

EUVD-2026-86663

In the Linux kernel, the following vulnerability has been resolved: net/sched: drr: clamp quantum in change class drrchangeclass rejects explicit quantum==0 but falls back to pschedmtu with no floor. With a crafted size table qdiscpktlen reaches 2 GiB, so quantum=1 or a zero pschedmtu on a...

CVE-2026-98009

The Linux kernel contains a vulnerability in the net/sched: ets component where the ets_qdisc_change() function falls back to psched_mtu() without a floor for bands lacking an explicit quantum. An attacker with CAP_NET_ADMIN privileges can use a crafted size table to cause qdisc_pkt_len to reach ...

CVE-2026-98010

The Linux kernel contains a vulnerability in the net/sched subsystem where the drr_change_class() function fails to properly clamp the quantum value during a fallback to psched_mtu(). Specifically, while explicit zeros are rejected, the absence of a floor allows a crafted size table to cause qdis...

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...

EUVD-2026-86661

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix NULL pointer dereference on unbind with fixed-link When the device tree describes a fixed-link and has no "mdio" child node, macbmiiinit returns early without allocating the MDIO bus, leaving bp-miibus as NULL. Two...

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...

EUVD-2026-86660

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject non-scalar bpfloop iteration counts bpfloop declares its nrloops argument as ARGANYTHING. Privileged programs may pass pointer values to such arguments, so checkfuncarg lets a pointer-valued R1 reach the helper-specif...

EUVD-2026-86659

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: Decoupling ep1inurb in caiaq dev The epqinurb object belonging to the caiaq device is coupled within the struct sndusbcaiaqdev. After usbsubmiturbepqinurb, GFPKERNEL executes successfully, epqinurb is successfully...

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...

EUVD-2026-86658

In the Linux kernel, the following vulnerability has been resolved: erofs: delimit inodeshare cache key components Previously, inodeshare keys were encoded as follows: fingerprint || domainid It would be better to have a separator between the fingerprint and domain ID so that the fingerprint won'...

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...

EUVD-2026-86657

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Serialize command queue publishing Serialize command queue publishing so software producer state advances only after a command is written and the hardware tail is updated. Wait for hardware consumption outside the...

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...

EUVD-2026-86656

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Do not reallocate GA log buffers on resume Commit c5e1a1eb9279 "iommu/amd: Simplify and Consolidate Virtual APIC AVIC Enablement" moved the GA log allocation from iommuinitpci to enableiommusvapic, which is called on...

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-2026-98001

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...
