CVE-2026-23063 pertains to the Linux kernel, specifically the UACCE accelerator framework. The issue arises in the queue release path for uacce_queue when resources could be freed concurrently (e.g., during poweroff -f with accelerators still active). The root cause is unsafe sequencing of operat...

CVE-2026-23067

CVE-2026-23067 centers on an integer signedness bug in the Linux kernel’s ARM IOMMU path (io-pgtable-arm). __arm_lpae_unmap() returned a size_t (unsigned) but could yield -ENOENT on error, turning into a large positive value on 64-bit systems and propagating through the call chain to __iommu_unma...

CVE-2026-23068

CVE-2026-23068 (Linux kernel) : The spi-sprd-adi driver could double-free the spi_controller on probe failure due to using spi_alloc_host() with devm_spi_register_controller(), then falling through to spi_controller_put() when a restart handler registration failed.

The revert sequence involves lock ord...

CVE-2026-23238

CVE-2026-23238 (Linux kernel — romfs): The romfs implementation in the kernel failed to honor the return value of sb_set_blocksize(), continuing a mount when the requested ROMBSIZE (e.g., 4096) was incompatible with the device’s logical_block_size (e.g., 32768). This could occur by using LOOP_SET...

CVE-2026-23266

CVE-2026-23266 : In the Linux kernel fbdev rivafb driver, nv3_arb() can divide by state->mclk_khz (derived from PRAMDAC MCLK PLL) if an attacker exposes a zero value, causing a divide error and kernel crash. The fix adds a zero-check for state->mclk_khz before division. Affected: fbdev/riva...

CVE-2026-23312

CVE-2026-23312 concerns the Linux kernel: the net: usb: kaweth driver did not validate USB endpoint counts/types when probing a device.

CVE-2026-31411

CVE-2026-31411: Linux kernel ATM signaling path (net/atm) allowed forged user pointers via sendmsg(), leading to potential memory safety risks. A fix adds find_get_vcc() to validate the vcc pointer against the vcc_hash and uses sock_hold() to keep the object alive during processing of signaling o...

CVE-2026-31450

CVE-2026-31450 describes a race in ext4 where ei->jinode was published to concurrent readers before jbd2_journal_init_jbd_inode() completed, allowing a non-NULL jinode to be observed with i_vfs_inode still NULL. The mitigated issue could lead to a crash when a reader passes jinode to jbd2_wait...

CVE-2026-31489

This CVE (CVE-2026-31489) affects the Linux kernel meson-spicc SPI controller driver. The vulnerability arises from a double-put: meson_spicc_probe() registers the controller with devm_spi_register_controller(), and the removal path erroneously calls spi_controller_put() again in meson_spicc_remo...

CVE-2026-31491

In the Linux kernel’s RDMA/irdma component, CVE-2026-31491 stems from depth calculation functions that fail to properly guard against U32_MAX inputs for SQ/RQ/SRQ sizes.

CVE-2026-43027

The CVE-2026-43027 vulnerability in the Linux kernel arises from nf_conntrack_helper_unregister() freeing a helper while expectations still reference it due to NULL data in nf_ct_expect_iterate_destroy(), leading to use-after-free when later access occurs. The fix is to pass the actual helper poi...

CVE-2026-43036

Summary (CVE-2026-43036) : The issue resides in the Linux kernel networking path, where gso_features_check() read IPv4 header offsets (iph->frag_off) in a way that could dereference uninitialized data when packets are injected via PF_PACKET paths. The root cause is unsafe header dereferencing ...

CVE-2026-43049

CVE-2026-43049 affects the Linux kernel HID logitech-hidpp driver (Logitech G920 force feedback). If force feedback init fails, resources may be torn down inconsistently, enabling a use-after-free (UAF) if userspace still references dangling objects. The fixed approach chose to warn but return su...

CVE-2026-43080

Summary of CVE-2026-43080 (Linux kernel) : The issue resides in the L2TP/PPP over L2TP code path where an oversized PPPoL2TP packet sent with UDP encapsulation can trigger an overflow of the 16‑bit UDP length field, causing the length to be trimmed and potentially sending malformed packets. The p...

CVE-2026-43093

CVE-2026-43093 is a Linux kernel issue in the xsk (AF_XDP) subsystem where headroom validation for UMEM was tightened in xdp_umem_reg(), addressing potential memory corruption of skb_shared_info and insufficient space for minimum-sized Ethernet frames. The fix accounts for 128-byte alignment as a...

CVE-2026-43205

CVE-2026-43205 affects the Linux kernel's dpaa2-switch handling. The defect arises from the driver obtaining sw_attr.num_ifs from firmware without validating it against DPSW_MAX_IF (64). This allows an out-of-bounds write in dpaa2_switch_fdb_get_flood_cfg() when num_ifs can reach 64, as it writes...

CVE-2026-43206

Summary: CVE-2026-43206 affects the Linux kernel’s drm/amdkfd component. The function kfd_event_page_set() writes KFD_SIGNAL_EVENT_LIMIT * 8 bytes using memset without validating the destination buffer size, allowing an unprivileged local user to trigger an out-of-bounds memory write and potentia...

CVE-2026-43258

CVE-2026-43258 concerns the Linux kernel: on Alpha systems, memory compaction can trigger user-space crashes and heap corruption due to insufficient TLB shootdown during page migration.

CVE-2026-43309

The CVE-2026-43309 issue affects the Linux kernel’s md raid and device-mapper (dm-raid) components. When stopping a RAID array managed by dm-raid, the system could hang because md_stop() attempted to flush the write-intent bitmap to metadata sub-devices that were already suspended. The fix preven...

CVE-2026-43328

Root cause: in the Linux kernel cpufreq governor, the error path in cpufreq_dbs_governor_init() could trigger a double free when kobject_init_and_add() fails. The kobject release path previously attempted cleanup via gov->exit(dbs_data) and kfree(dbs_data) twice. The fix keeps a direct kfree(d...

CVE-2026-43345

Summary: The CVE concerns the Linux kernel IPA driver. For IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to CH_C_CNTXT_1. The register definition intended to define this field in CH_C_CNTXT_1 but used the old identifier ERINDEX instead of CH_ERINDEX, causing an incorrect event rin...

CVE-2026-43349

The CVE-2026-43349 entry concerns the Linux kernel’s Flash-Friendly File System (f2fs). The issue arises when f2fs_finish_read_bio() may access uninitialized data in a folio if a read from the device fails, triggering an uninitialized-value access in f2fs_sanity_check_node_footer. The root cause,...

CVE-2026-43357

The CVE-2026-43357 entry concerns the Linux kernel iio: gyro: mpu3050-core driver.

Multiple sources (Red Hat, Debian,...

CVE-2026-43430

The issue CVE-2026-43430 affects the Linux kernel USB driver for yurex. A race condition occurs in the probe path where the bbu field is not initialized before the URB completion handler uses it, creating a window during which descriptor data can be overwritten by concurrent probing. This can lea...

CVE-2026-43432

CVE-2026-43432 relates to the Linux kernel USB xHCI driver. The error path in usb/xhci_disable_slot() previously freed only the command structure (via kfree), leaking the associated completion structure.

CVE-2026-43436

The CVE-2026-43436 vulnerability affects the Linux kernel ALSA USB-audio driver (Scarlett2 mixer quirk). A malformed USB descriptor can trigger a NULL dereference in scarlett2_find_fc_interface() due to assuming an endpoint exists. The patch adds a sanity check for bNumEndpoints and skips invalid...

CVE-2026-43472

The CVE describes a Linux kernel unshare(2) bug: when CLONE_NEWNS is requested and current->fs wasn’t previously shared, copy_mnt_ns() could receive a non-private fs_struct. If copy_mnt_ns() succeeds but a subsequent copy_cgroup_ns() fails, the destroyed namespace can leave current->fs->...

CVE-2026-43489

The CVE-2026-43489 issue concerns the Linux kernel liveupdate code path for LUO files, specifically luo_file.retrieve_status. The bug arises because on a failed retrieve, luo_retrieve_file() returns an error without recording that a retrieve was attempted or its error code. This can cause an erro...

CVE-2026-43497

The CVE-2026-43497 issue affects the Linux kernel fbdev path (udlfb/dlfb) where dlfb_ops_mmap maps vmalloc framebuffer pages without vm_ops, preventing mmap tracking. This allowed stale user PTEs to coexist with freed kernel pages after dlfb_realloc_framebuffer() via FBIOPUT_VSCREENINFO, causing ...
