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-2026-46267

CVE-2026-46267 affects the Linux kernel NFC HCI SHDLC subsystem. The root cause is that timers and state-machine work can remain active during llc_shdlc_deinit(), which purges SHDLC skb queues and frees the llc_shdlc structure while callbacks may still access SHDLC state and queues. If teardown r...

CVE-2026-46305

CVE-2026-46305 affects the Linux kernel, specifically the staging/rtl8723bs path. The issue arises when kzalloc_flex()’s return value is used without checking for allocation failure, leading to a potential NULL pointer dereference when accessing the allocated structure. The fix guards access to t...

CVE-2026-53027

CVE-2026-53027 affects the Linux kernel's fs/ntfs3 component. A missing load of the vcn0 runs when a compressed/sparse attribute is frame-aligned can leave vcn0 in a different attribute segment than vcn, causing run_lookup_entry() to return SPARSE_LCN and triggering WARN_ON(1). The documented fix...

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...

CVE-2026-53147

The CVE-2026-53147 issue affects the Linux kernel Thunderbolt XDomain handling. tb_xdp_handle_request() casts the received packet buffer to protocol-specific structs without confirming that the allocation is large enough for the target type. A peer could send a minimal XDomain packet that passes ...

CVE-2026-53181

CVE-2026-53181 affects the Linux kernel vsock/vmci stack. On failing handshake, vmci_transport_recv_listen() could leave sk_ack_backlog incremented (due to missing sk_acceptq_removed() call), allowing backlog growth toward sk_max_ack_backlog and a possible listener denial of new connections (-ECO...

CVE-2026-53316 : In the Linux kernel, the DRM/AMD ras subsystem suffers a NULL pointer dereference in ras_core_ras_interrupt_detected() when ras_core is NULL and ras_core->dev is accessed in the error path. This has been fixed in kernel code (see commits referenced by the CVE). The vulnerabili...

CVE-2026-53337

CVE-2026-53337 affects the Linux kernel bonding code. In bond_do_ioctl(), slave_dev is obtained via __dev_get_by_name() and may be NULL, yet slave_dbg(bond_dev, slave_dev, …) dereferences slave_dev->name before the NULL check, causing a NULL pointer dereference and a potential local DoS when a...

CVE-2026-63798

This CVE concerns the Linux kernel IRQ subsystem for the irqchip/imgpdc driver. The vulnerability arises because, during probe, the driver allocates domain generic chips and installs chained interrupt handlers, but on removal these resources may not be cleaned up: generic chips stay on the global...

CVE-2022-50312

CVE-2022-50312 affects the Linux kernel driver for serial jsm: leaks in probe due to incomplete unwind in error paths.
