CVE-2026-53248

In Linux kernel, the airoha net driver has a use-after-free in metadata_dst teardown (CVE-2026-53248). The airoha_metadata_dst_free() function frees the metadata_dst with kfree() immediately, bypassing the RCU grace period, while the RX path may hold a non-refcounted pointer from skb to the dst v...

CVE-2026-53261

The CVE-2026-53261 issue affects the Linux kernel devlink path: when a devlink instance obtains a nested relation before registration and probe later fails, devl_unregister() does not run for an unregistered instance, leaking devlink->rel. The fix releases any pending relation from devlink_fre...

CVE-2026-63807 concerns the Linux kernel KVM: x86/mmu path. The issue arises when recovering hugepages in the shadow MMU, where the base guest frame number (gfn) of a shadow page must be verified to be within the target memslot before querying the max mapping level. If the gfn is not pre-checked,...

CVE-2026-64098

CVE-2026-64098 affects the Linux kernel’s VirtIO GPU driver. The issue arises when virtio_gpu_cursor_plane_update() and virtio_gpu_resource_flush() acquire the framebuffer dma_resv via virtio_gpu_array_lock_resv() and ignore the return value. The lock can fail (-EINTR or -ENOMEM), leaving the res...

CVE-2026-64160

CVE-2026-64160 involves a Linux kernel netfs issue where tearing could occur in remote_i_size and zero_point updates. The fix copies i_size_read() and i_size_write() and uses the same seqcount as i_size to prevent i_size_seqcount corruption, and requires netfslib and filesystems using it to hold ...

CVE-2026-64171

The CVE refers to the Linux kernel i2c Tegra driver. Root cause: a mutex_lock failure in tegra_i2c_mutex_lock() could return without pm_runtime_put(), leaking the runtime PM reference acquired by pm_runtime_get_sync(). Consequence: the affected device could fail to enter runtime suspend, increasi...

CVE-2026-64175

CVE-2026-64175 concerns the Linux kernel’s iwlwifi/iwl_mld stack. When the Intel BE201 Wi‑Fi 7 firmware restarts after a crash, the TX path lacked a guard like the RX path, so iwl_mld_tx_from_txq() could dequeue and push frames to the transport layer while the firmware was dead. This caused iwl_t...

CVE-2026-64178

The CVE-2026-64178 issue is in the Linux kernel Bluetooth BNEP implementation. A use-after-free can occur when reading dev->name during bnep_add_connection() because the underlying net_device may be freed concurrently by bnep_del_connection(). The root cause is that bnep_add_connection() did n...

CVE-2026-64211

CVE-2026-64211 affects the Linux kernel SRCU: during CPU state transitions, tree SRCU could queue workqueue callbacks to CPUs that are not online or will never be online (including imaginary CPUs).

CVE-2026-64219

CVE-2026-64219 affects the Linux kernel drm/amd/display path, specifically dc_process_dmub_aux_transfer_async, where payload->length is copied into a 16-byte stack buffer (dpaux.data[16]) guarded only by an ASSERT(). If length > 16, this can cause a stack-based overflow; additionally, dc-&g...

CVE-2026-64282

CVE-2026-64282 affects Linux kernel KVM on arm64. Root cause: kvm_translate_vncr() may race MMU notifier and fail to release a faulted PFN, leading to PFN leak/resource exhaustion. Fix: add kvm_release_faultin_page() for unused PFNs. Public advisories (Ubuntu/OpenSUSE/SUSE/RH/Debian OSV entries) ...

CVE-2026-64284

CVE-2026-64284 — Linux kernel (KVM/x86): The vulnerability involves moving the handling of fastpath userspace exits into vendor code so KVM can run vendor-specific operations before userspace gains control of the vCPU. The description notes that, for VMX (and soon SVM), KVM must flush the PML buf...

CVE-2026-64302

CVE-2026-64302 is a memory leak in the Linux kernel (x86/mm) introduced by commit bf9e4e30f353, which switched page-table freeing to pagetable_free(). The function was also used to free vmemmap pages , but since vmemmap pages are not compound pages, __free_pages(page, compound_order(page)) only f...

CVE-2026-64310

CVE-2026-64310 is a denial-of-service flaw in the Linux kernel's crypto: ccp component (AMD Secure Encrypted Virtualization). When SEV initialization fails while KVM is actively running VMs, a local user with access to /dev/sev can trigger SEV-only ioctls (e.g., SEV_PDH_GEN). The buggy sev_move_t...

CVE-2026-64388

Summary: CVE-2026-64388 affects the Linux kernel SMB client when using SMB3 POSIX Extensions, where chown/chgrp updates could be ignored unless CIFS_MOUNT_CIFS_ACL or CIFS_MOUNT_MODE_FROM_SID are also set. The root cause is a missing check for posix_extensions in cifs_setattr_nounix() during UID/...

CVE-2026-64393

The CVE-2026-64393 issue affects the Linux kernel ksmbd component. SMB2 SET_INFO handlers performed path-based VFS checks using the current ksmbd worker credentials rather than the credentials that opened the handle, potentially bypassing security checks. The fix captures the opener credentials a...

CVE-2026-64404

CVE-2026-64404 is a NULL pointer dereference in the Linux kernel's Bluetooth ISO subsystem , specifically in the iso_conn_big_sync() function. The function drops the socket lock to call hci_get_route() and re-acquires it, but dereferences iso_pi(sk)->conn->hcon without re-validating that co...

CVE-2026-64409

CVE-2026-64409 is a denial-of-service vulnerability in the Linux kernel's btmtksdio Bluetooth SDIO driver. The root cause is an incorrect time_is_before_jiffies() check in btmtksdio_txrx_work(): the timeout condition is inverted, so once the 5-second limit is exceeded the loop condition becomes a...

CVE-2026-64415

CVE-2026-64415 is a softlockup vulnerability in the Linux kernel's mm/swap component, specifically in swap_reclaim_full_clusters(). Under heavy memory and swap stress (observed during LTP stress on a 320-CPU arm64 machine with ~1 TB RAM and an 8.6 GB swap device), the function can run for an exte...

CVE-2026-64439

CVE-2026-64439: In the Linux kernel, the krb5 AEAD path could free a buffer while an async AEAD worker still held a pointer, causing a use-after-free (KASAN). The fix filters out async AEAD implementations at allocation time in krb5_aead_encrypt()/krb5_aead_decrypt() and corresponding rfc3961_sim...

CVE-2022-49955

Summary of CVE-2022-49955 : This vulnerability concerns the Linux kernel’s powerpc/rtas code, where MSR[HV] handling for IBM Cell during RTAS entry could crash the system.

CVE-2022-50244

CVE-2022-50244 affects the Linux kernel code path in cxl_pci_init_afu|adapter() where a failed device_register() leaves a not-added device and leads to a potential null pointer dereference if device_unregister() is called in the error path. The fix splits unregister logic into device_del() and pu...

CVE-2022-50257

The CVE-2022-50257 issue is in the Linux kernel Xen grant handling (xen/gntdev) where partial grant mapping failures could leak grants. In paravirtualized domains (use_ptemod = true), alloced was not updated for all successful map_ops or kmap_ops, risking incorrect live_grants and leaks. The fix ...

CVE-2022-50271

CVE-2022-50271 affects the Linux kernel’s vhost/vsock code. The issue arises when copying large files over SFTP over vsock, where data sizes commonly reach 32 kB and kmalloc may allocate many 32 kB chunks, leading to a page allocation failure (example: vhost-5837). The root cause is an inefficien...

CVE-2022-50296

CVE-2022-50296 affects the Linux kernel where cpu_max_bits_warn() would warn when CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are enabled while displaying /proc/cpuinfo. The root cause is using NR_CPUS to iterate CPUs instead of the runtime limit nr_cpu_ids, which leads to a runtime war...

CVE-2022-50314

The CVE-2022-50314 issue affects the Linux kernel nbd subsystem. When a signal interrupts nbd_start_device_ioctl() while waiting for inflight I/Os to complete, a hung task could occur. The fix clears the queue (not just shutdown) on signal interruption to nbd_start_device_ioctl(), mitigating the ...

CVE-2022-50322

CVE-2022-50322 affects the Linux kernel RTC driver (msc313) where a function prototype mismatch in msc313_rtc_probe() was exposed under Clang with kCFI (CONFIG_CFI_CLANG). The indirect call validation failed when clk_disable_unprepare() did not match devm_add_action_or_reset() callback prototypes...
