CVE-2026-89528

CVE-2026-89528 affects the Linux kernel's svcrdma (RPC-over-RDMA) server. Individual Read segment lengths are validated at decode time, but nothing prevents a remote requester from sending multiple segments whose cumulative length exceeds the rq_pages array budget. When one segment fills the page...

CVE-2026-89527

This Linux kernel vulnerability affects the svcrdma (RPC/NFS RDMA server) subsystem. The root cause is an improper error-path cleanup in svc_rdma_create(): when svc_rdma_create_listen_id() fails, the code calls kfree() on the transport structure, bypassing svc_xprt_free(). This leaks the net name...

CVE-2026-89526

A vulnerability in the Linux kernel's svcrdma (NFS/RDMA server) component allows a remote attacker to craft an RPC/RDMA Read chunk position field that bypasses validation. In the single-chunk path, a position past the inline body underflows the tail length, exposing adjacent slab memory to the up...

CVE-2026-89525

This vulnerability affects the Linux kernel's UDF 1.50 virtual partition mapping in the function udf_get_pblock_virt15() . The root cause is an off-by-one bounds check : the code rejected only indexes greater than s_num_entries, but valid VAT indexes are strictly below that value. A crafted UDF i...

CVE-2026-89524

CVE-2026-89524 is an integer underflow in the Linux kernel's ath6kl Wi-Fi driver . In ath6kl_cfg80211_connect_event(), fixed IE offsets are subtracted from assoc_req_len (−4) and assoc_resp_len (−6), both of type u8, with no lower-bound check. When an association request or response is shorter th...

CVE-2026-89523

This vulnerability affects the MediaTek mt7925 Wi-Fi driver in the Linux kernel (part of the mt76 subsystem). A pending delayed work item (mlo_pm_work) may continue executing after the device is reset, suspended, or unregistered, leading to a use-after-free on vif/bss data or MCU commands sent to...

CVE-2026-89522

CVE-2026-89522 is a use-after-free in the Linux kernel's media/ipu7 staging driver . When a probe step such as isys_fw_log_init() fails after isys_notifier_init() has registered a V4L2 async notifier, the error cleanup path calls isys_unregister_devices() but never unregisters the async notifier....

CVE-2026-89521

CVE-2026-89521 affects the Linux kernel's core scheduling subsystem. When a ->pick_task() implementation releases the run queue (rq) lock, the selection state derived in pick_next_task() becomes invalid, allowing an interleaving selection to commit an incorrect (uncookied) pick or skew forceid...

CVE-2026-89520

CVE-2026-89520 is a race condition in the Linux kernel's core scheduling component. When pick_next_task() releases the runqueue lock during task selection, sibling locks become momentarily free, allowing __sched_core_flip(false) to rebind rq_lockp() mid-selection. The selection then resumes on sp...

CVE-2026-89518

This CVE affects the Linux kernel 's sched_ext (BPF scheduler extension) subsystem. Under core scheduling , ops.dispatch() may execute on a CPU different from the dispatched run queue's, but several kfunc paths incorrectly assumed this_rq() always coincides with the dispatched rq. Specifically, s...

CVE-2026-89519

CVE-2026-89519 affects the Linux kernel's sched_ext (extensible scheduler) subsystem. The root cause is that SCX_RQ_BAL_KEEP , an rq-level flag used to tell the picker to keep running the previous task, becomes stale under core scheduling : because selections interleave through dispatch lock drop...

CVE-2026-89517

CVE-2026-89517 affects the Linux kernel's sched_ext (sched_ext) subsystem under core scheduling . Since commit 4c95380701f5, sched_ext's dispatch runs inside pick_next_task() and can drop the core-wide rq lock. When selections on the same core interleave through this dropped lock, they corrupt ea...

CVE-2026-89516

This CVE affects the Linux kernel in the sched_ext (scheduling extensions) subsystem. The vulnerability occurs in process_deferred_reenq_users(): when scx_bpf_dsq_reenq() queues a deferred reenqueue that executes from run_deferred() (not ops.dispatch()), and the associated DSQ (dispatch queue) is...

CVE-2026-89515

CVE-2026-89515 is a Linux kernel vulnerability in the SCSI core subsystem, specifically in scsi_alloc_sgtables(). When processing the last unaligned scatterlist element, padding bytes (pad_len) remain uninitialized , causing an uninit-value access in __dma_map_sg_attrs (detected by KMSAN). The tr...

CVE-2026-89514

In the Linux kernel , the scsi: fnic driver's fnic_fcoe_process_vlan_resp() function allocates a VLAN descriptor using kzalloc_obj() with the default GFP_KERNEL flag while holding vlans_lock via spin_lock_irqsave(). Since GFP_KERNEL may sleep, this is invalid in the atomic context and can trigger...

CVE-2026-89512

CVE-2026-89512 is a device reference leak in the Linux kernel's remoteproc: scp subsystem. When the driver attempts to look up the SCP device's driver data before the driver has been bound, a reference to the device is taken but not properly dropped if the lookup fails. Holding a device reference...

CVE-2026-89513

CVE-2026-89513 is an integer overflow in the Linux kernel's KVM (RISC-V) component. The SBI PMU EVENT_GET_INFO handler stores num_events * sizeof(*einfo) in a 32-bit integer; on RV64, a guest-supplied num_events = 0x10000001 truncates the allocation to 16 bytes while KVM still loops over the orig...

CVE-2026-89511

CVE-2026-89511 is a NULL pointer dereference in the qede driver (QLogic 10GbE Ethernet) of the Linux kernel , leading to a kernel panic and Denial of Service (CVSS 3.1: 7.5 HIGH , AV:N/AC:L/PR:N). The root cause is a dropped assignment of tpa_info->buffer.data in qede_tpa_start(), introduced b...

CVE-2026-89510

CVE-2026-89510 is a use-after-free vulnerability in the Linux kernel's RDMA/cxgb4 (Chelsio) driver. When c4iw_remove() frees the device context (ctx->dev) while the reg_work work item—queued by c4iw_uld_state_change()—is still pending or executing, c4iw_register_device() may access already-fre...

CVE-2026-89509

CVE-2026-89509 affects the Linux kernel 's RDMA/ionic driver . The root cause is that the ionic driver was merged without adapting to the rdma_zalloc_drv_obj() API introduced by commit 7e53b31acc7f, which requires drivers to embed struct rdma_counter in a driver-specific struct and register its s...
