The CVE-2026-46142 issue affects the Linux kernel’s net: libwx code, where reading the PF-restricted WX_CFG_PORT_ST register during VF initialization can trigger an illegal register access, potentially causing a system hang. The root cause is that a VF’s bus function ID can be read directly from ...
CVE-2026-46154
CVE-2026-46154 affects the Linux kernel sched_ext functionality. Root cause: in cgroup setters, scx_group_set_{weight,idle,bandwidth}() cache the scx_root before acquiring scx_cgroup_ops_rwsem, enabling a window where the pointer can become stale if a scheduler is disabled and freed (via RCU) and...
CVE-2026-46161
CVE-2026-46161 affects the Linux kernel md/raid10 code: setup_geo() may divide by zero when fc (far copies) is 0, since it derives geo->far_set_size from disks/fc without validating zero. The fix validates nc and fc after extraction and returns -1 if either is zero. Connected OSV entries show ...

CVE-2026-46184
CVE-2026-46184 relates to the Linux kernel sound/ua101 driver. The root cause is a missing sanity check for bNrChannels in detect_usb_format(), which can lead to a division by zero in playback_urb_complete() and capture_urb_complete() when a device reports bNrChannels = 0. The USB core does not v...
CVE-2026-46229
The CVE-2026-46229 issue affects the Linux kernel’s DRM/AMDKFD path: KFD VRAM allocations could leave stale data because AMDGPU_GEM_CREATE_VRAM_CLEARED was not applied in the KFD code path, unlike the GEM/user paths which already set VRAM_CLEARED. This allowed stale page-table remnants to leak in...
CVE-2026-46251
The CVE-2026-46251 issue is a Linux kernel Btrfs vulnerability where, when EXTENT_TREE_V2 is enabled, the block_group_tree may be added to switch_commits while still on the dirty_list, causing invalid list manipulation and corruption of block_group_root->dirty_list. This corruption can propaga...
CVE-2026-46284
CVE-2026-46284 affects the Linux kernel mm/hugetlb parameter parsing path. When hugepages, hugepagesz, or default_hugepagesz are supplied on the kernel command line without an '=' separator, early-boot parameter parsing passes NULL to hugetlb_add_param(), which dereferences NULL in strlen(), pote...
CVE-2026-46286
CVE-2026-46286 describes a Linux kernel issue in leds: qcom-lpg, where selecting high-resolution values from a 5-entry array uses FIELD_GET() to pull from a 3-bit register, risking out-of-bounds reads. The referenced fix adds a bounds check before indexing, preventing overflow and potential incor...
CVE-2026-52920
The CVE-2026-52920 involves the Linux kernel netfilter xt_policy module, where strict inbound policy matching previously consumed info->pol[] in an incorrect order when multiple transforms were applied. Root cause: match_policy_in() iterates sec_path entries from last to first, violating the f...
CVE-2026-52922
CVE-2026-52922 affects batman-adv in the Linux kernel. The root cause is that batadv_dat_forward_data() duplicates an skb via pskb_copy_for_clone() but does not verify the allocation result before passing the skb to batadv_send_skb_prepare_unicast_4addr(), which can dereference a NULL skb and tri...
CVE-2026-53018
CVE-2026-53018 affects the Linux kernel f2fs filesystem. The issue occurs during garbage collection when a page has been moved and updated, but the system re-reads it from an outdated location, triggering a kernel BUG in mm/filemap.c and potentially a DoS. The vulnerability is addressed by a comm...
CVE-2026-53072
The CVE-2026-53072 vulnerability affects the Linux kernel Bluetooth subsystem, specifically hci_conn_request_evt() when HCI_PROTO_DEFER is active. The issue arises because hci_connect_cfm(conn) is called without holding hdev->lock, breaking the expected lock discipline and allowing a Use-After...
CVE-2026-53100
CVE-2026-53100 affects the Linux kernel mt76 wireless driver. The deadlock occurs when remain-on-channel logic calls mt76_set_channel() while dev->mutex is already held by remain_on_channel/roc_complete, since mt76_set_channel() also locks the mutex. The fix replaces mt76_set_channel() with __...
CVE-2026-53122
CVE-2026-53122: Linux kernel bug in btrfs where flushoncommit can deadlock a reflink with a pending transaction commit when copying an inline extent beyond i_size. The issue arises from locking sequences between reflink/commit paths and delalloc/ordered extents, leading to a cycle where two tasks...
CVE-2026-53125
CVE-2026-53125 affects the Linux kernel. When user-space writes “clear” to /sys/block/md*/md/array_state, md_attr_store() drops the mddev reference before sysfs_unbreak_active_protection(), which can cause the last kobject reference to be dropped while the mddev is still eligible for deletion. Th...
