CVE-2026-74325

CVE-2026-74325 concerns the Linux kernel’s mt76 Wi-Fi driver. The fix replaces a plain kfree() with kfree_rcu() for the offchannel mlink object in mt76_put_vif_phy_link to ensure memory is not freed while still potentially accessed under RCU. The root cause is that rcu_assign_pointer(NULL) only p...

CVE-2026-74326

The CVE-2026-74326 entry describes a resource leak in the Linux kernel WiFi subsystem for the mt76 mt7921 driver. If pcim_iomap_region() or devm_kmemdup() fail during probe, the code returns without cleaning up previously allocated resources, specifically the mt76_device created by mt76_alloc_dev...

CVE-2026-74324

Summary: CVE-2026-74324 affects Linux kernel wireless stack, specifically mt76/mt7925 testmode query handling. In mt7925_tm_query(), the response skb is copied with memcpy(evt_resp, skb->data + 8, MT7925_EVT_RSP_LEN) without validating length. MT7925_EVT_RSP_LEN is 512, so a firmware response ...

CVE-2026-74323

CVE-2026-74323 affects the Linux kernel wifi driver for the MT76 MT7996. The vulnerability occurs in the mt7996_tx_prepare_skb() path: if link_conf or link_sta lookups fail, the driver leaks an already allocated TX token. The fix releases the token in error paths to prevent the leak. The issue ha...

CVE-2026-74322

In the Linux kernel, the wifi/mt76 mt7996 path is affected by CVE-2026-74322. The vulnerability stems from a possible NULL pointer dereference in mt7996_mac_write_txwi_80211() when handling injected frames (e.g., radiotap) where info->control.vif can be NULL. The code originally calls ieee8021...

CVE-2026-74321

In the Linux kernel CVE-2026-74321, the bug is in btrfs: __btrfs_run_delayed_refs loop where, if btrfs_select_ref_head() returns ERR_PTR(-EAGAIN), the code previously could end up dereferencing an invalid pointer (locked_ref) after the next iteration. The fix ensures that when an ERR_PTR(-EAGAIN)...

CVE-2026-74320

CVE-2026-74320 : In the Linux kernel fbdev sm501fb driver, the OF binding code had multiple memory-safety issues: use-after-free, buffer overrun, and memory leaks. The fix addresses edid_data not being freed when probes fail or def_mode is set; double-free risk when both CRT and PANEL are enabled...

CVE-2026-74319

CVE-2026-74319 documents a deadlock in the Linux kernel's BTRFS when performing data relocation on zoned filesystems. The relocation process can deadlock while waiting for a space reservation ticket that it itself would free, because the ticket cannot be fulfilled. The fix introduces a new flush ...

CVE-2026-74318

CVE-2026-74318 concerns the Linux kernel, specifically a deadlock in btrfs when cloning an inline extent while using the flushoncommit option. The issue occurred during reflink/transaction commit, where copying inline extent data to a destination file could deadlock if the destination offset was ...

CVE-2026-74316

The CVE-2026-74316 entry describes a Linux kernel vulnerability in NFSD: nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT handling. When a client sends FREE_STATEID for an admin-revoked layout stid, the default branch does not unhash or release the stid, leaving it in the IDR and per-client list u...

CVE-2026-74317

CVE-2026-74317 : In the Linux kernel, the ixgbe driver incorrectly configures XDP TX queues via netif_set_xps_queue, causing a KASAN slab-out-of-bounds and a warning during XDP program load on systems with many CPUs. The fix is to skip XPS configuration for XDP TX queues. The vulnerability is res...

CVE-2026-74315

CVE-2026-74315 (Linux kernel) : The vulnerability arises in lockd/nlm4svc_lookup_file where file_handle hashing used the first LOCKD_FH_HASH_SIZE bytes of nfs_fh.data regardless of fh.size, causing inconsistent bucket lookups when a client presents a shorter file handle. A commit changed populati...

CVE-2026-74313

The CVE-2026-74313 issue affects the Linux kernel under the VDUSE path. Specifically, vduse_dev_open() currently looks up a vduse_dev via an IDR lookup and then acquires dev->lock after vduse_lock is dropped, creating a window where VDUSE_DESTROY_DEV could remove and free the same object befor...

CVE-2026-74314

CVE-2026-74314 relates to the Linux kernel BPF map value handling. The description shows a fix for canceling field cleanup on map value recycle: during updates/deletes, fields no longer are eagerly freed via bpf_obj_free_fields(); instead, bpf_obj_cancel_fields() performs only NMI-safe cleanup fo...

CVE-2026-74312

The CVE-2026-74312 entries describe a Linux kernel vulnerability in vhost/vdpa where mmap and fault paths use vma->vm_pgoff as a virtqueue index without proper bounds validation against v->nvqs. This allowed an out-of-range queue index to reach driver callbacks via get_vq_notification(), un...

CVE-2026-74311

CVE-2026-74311 affects the Linux kernel virtio rtc path. The bug occurs when viortc_restore() calls viortc_init_vqs() without removing old virtqueues, enabling vp_del_vqs() to reference a NULL info pointer in vp_del_vq() and crash the guest kernel during restore. The fix deletes stale virtqueues ...

CVE-2026-74310

The CVE affects the Linux kernel vhost/net zerocopy path. The bug arises when vhost_zerocopy_complete() treats every ubuf callback as a completed descriptor, dereferences ubuf->ctx, and updates state while a cloned skb still holds the same ubuf_info refcount. This can allow a backend reset to ...

CVE-2026-74309

The CVE-2026-74309 entry documents a Linux kernel issue in the vdpa/octeon_ep component where interrupt handling incorrectly mapped IRQs to rings. The root cause is assuming irq - irqs[0] to locate the IRQ index; the fix updates the code to look up the IRQ index within oct_hw->irqs, allowing n...

CVE-2026-74308

Summary: CVE-2026-74308 affects the Linux kernel ext4 in the data=journal scenario. The bug was that ext4_journalled_write_end() could call ext4_write_inline_data_end() without verifying EXT4_STATE_MAY_INLINE_DATA, if a prior inline data conversion failed. This could leave i_inline_size unexpande...

CVE-2026-74306

Summary (CVE-2026-74306): In the Linux kernel, the vfio/qat path is affected by a race in qat_vf_resume_write() where a bounds check uses filp->f_pos before taking migf->lock. The code then copies into the migration-state buffer after acquiring the lock and rereading the shared file positio...
