CVE-2026-46129

CVE-2026-46129 concerns the Linux kernel’s btrfs subsystem. In the create_space_info() error path, if kobject_init_and_add() fails, the chain leads to a double free of space_info due to both a direct kfree and a later release via space_info->kobj. The fix changes cleanup so that after kobject_...

CVE-2026-46169

The CVE-2026-46169 case concerns the Linux kernel HFS Plus (HFS+) filesystem. The root cause is that hfs_brec_read() validates only that entrylength fits a buffer but does not confirm that the on-disk catalog record size matches the expected type, allowing partial reads on corrupted filesystems. ...

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-2026-53147

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-2026-53150

CVE-2026-53150 affects the Linux kernel Thunderbolt validator. The bug arises when tb_property_entry_valid() accepts zero-length TEXT entries for DIRECTORY/DATA/TEXT, enabling a null-termination underflow (writes at property->value.text[length*4 - 1] with length 0). A fix rejects zero-length e...

CVE-2026-53191

CVE-2026-53191 affects the Linux kernel io_uring/net path.

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-2026-64124

CVE-2026-64124 concerns the Linux kernel net: devmem: bind via dma-buf with non-page-aligned size or SG length. The issue arises because net_devmem_bind_dmabuf() trusts dmabuf->size and sg_dma_len() to be multiples of PAGE_SIZE without checking, causing an out-of-bounds access: tx_vec is sized...

CVE-2026-64242

The CVE-2026-64242 issue affects the Linux kernel USB gadget net2280 driver. A double free could occur in the probe error path: usb_initialize_gadget() registers gadget_release() as the release callback, so net2280 is freed via gadget_release() when the gadget reference drops. The probe error pat...

CVE-2026-64246

CVE-2026-64246 affects the Linux kernel: a use-after-free in power: reset handling for linkstation-poweroff.

CVE-2026-64285

CVE-2026-64285 affects the Linux kernel KVM SEV SNP path. When populating a guest’s initial CPUID data, KVM may pin a source page as writable and write back data if the userspace-provided CPUID data is rejected by trusted firmware, risking clobbering read-only memory due to kernel mappings. Multi...

CVE-2026-64289

CVE-2026-64289 affects the Linux kernel in the iommufd path, where iommufd_hwpt_invalidate() accepts user-controlled entry_num and entry_len.

CVE-2026-64331

CVE-2026-64331 is a NULL pointer dereference in the Linux kernel's usbip vudc subsystem. The root cause is that vep_alloc_request() never initialized vrequest->udc, so when FunctionFS AIO cancellations arrived in vep_dequeue, a NULL UDC reference caused a kernel oops. The bug reportedly existe...

CVE-2026-64342

CVE-2026-64342 is a use-after-free vulnerability in the Linux kernel's iowarrior USB driver . Submitted write URBs are not stopped on close(), so they must be stopped unconditionally on disconnect() to prevent the completion handler from accessing freed memory. NVD scores it 7.8 HIGH (AV:L/AC:L/P...

CVE-2026-64403

CVE-2026-64403 covers a Linux kernel Bluetooth L2CAP bug. l2cap_get_conf_opt() derives the option length from opt->len and dereferences opt->val before ensuring the buffer contains opt->len bytes, allowing an out-of-bounds read (up to 4 bytes) before a check. Callers detect malformed opt...

CVE-2026-64444

CVE-2026-64444 - Linux kernel (rtl8723bs) OOB read in OnAssocRsp() IE loop . The vulnerability arises in the IE processing loop of OnAssocRsp(), which advances by (pIE->length + 2) per iteration but only checks i length from pframe[pkt_len] (past the buffer) and, even when headers are in bound...

CVE-2026-64452

CVE-2026-64452 (Linux kernel 6LoWPAN) involves a race condition in 6LoWPAN’s Next Header Compression (NHC) handling that can cause a use-after-free in lowpan_nhc_do_uncompression when an NHC descriptor is freed while another path accesses nhc->name in an error path. The issue arises from holdi...
