CVE-2026-74330

The CVE-2026-74330 entry specifies a Linux kernel fix for configfs lockless traversals of ->s_children. The issue allowed cursor movement or freeing under lock protection of the parent directory, potentially enabling invalid cursor states via lseek() despite entry protection from removal. The ...

CVE-2026-74328

CVE-2026-74328 concerns the Linux kernel: an iommufd-related issue where destroying page content after detaching from a dmabuf could occur while the mutex is still in use via invalidation callbacks. The vulnerability is addressed by ensuring the page content is not destroyed until the dmabuf is f...

CVE-2026-74327

CVE-2026-74327 affects the Linux kernel vmalloc area handling. The issue is a NULL pointer dereference in is_vm_area_hugepages() because find_vm_area() can return NULL for an invalid vmalloc address; the patch adds a check on the returned pointer before dereferencing it to prevent a kernel crash....

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-2026-74322

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-2026-74323

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-2026-74321

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-2026-74319

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-2026-74320

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-2026-74318

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-2026-74317

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-2026-74316

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-2026-74315

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 ...
