CVE-2026-68428

The CVE describes a use-after-free in KVM’s x86/mmu related to vendor module reloads, where mmu_destroy_caches() leaves pointers to caches (pte_list_desc_cache and mmu_page_header_cache) in kvm.ko. When a vendor module unload occurs while kvm.ko remains loaded, a subsequent cache initialization c...

CVE-2026-68330

CVE-2026-68330 relates to the Linux kernel net/airoha NPU mailbox handling. The issue arises because airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE, while some callers expect the NPU to write the response back into the same buffer. On non‑cache‑coherent architectures (e.g...

CVE-2026-68233

In the Linux kernel DRM/VC4 subsystem, CVE-2026-68233 addresses a use-after-free-like race where a timer callback (BO cache timer) can be rearmed by time_work during teardown. vc4_bo_cache_destroy() deletes the timer and cancels the work, but the cancelled work can rearm the timer and queue work ...

CVE-2026-68168

The CVE describes a Linux kernel AFS fix: afs_edit_dir_remove() now uses afs_dir_get_block() to obtain block 0 instead of afs_dir_find_block(), because the latter caches the found block in afs_dir_iter and can switch the page if a subsequent find occurs. This change aligns with the existing afs_e...
