CVE-2026-74518

CVE-2026-74518 — Linux kernel: mm/hugetlb list corruption in allocate_file_region_entries() fixed. The bug allowed a corrupted resv->region_cache when top‑up relied on list_splice() leaving a stale source head during a retry loop under concurrent mappings of hugetlbfs. The fix uses list_splice...

CVE-2026-74516

The CVE-2026-74516 issue affects the Linux kernel (KVM/SMV) where, if AVIC is inhibited while L2 is active, the host may run L1 with AVIC disabled and with x2APIC MSR intercepts also disabled. This allows L1 to access the host APIC state, trigger arbitrary interrupts, modify task priority, and co...

CVE-2026-74517

CVE-2026-74517 : Linux kernel/KVM local issue where delaying and later processing of I/O APIC EOI during VM destruction could cause a use-after-free. The documented fix cancels and flushes the delayed EOI work in the pre-destroy phase before vCPUs are destroyed to prevent injecting IRQs after des...

CVE-2026-74515

CVE-2026-74515 concerns the Linux kernel, specifically KVM on s390 for PCI (zPCI). The issue arises when enabling adapter interrupt forwarding: the MPCIFC instruction forbids registering interrupts without unregistering first, so a second or repeated enable request for the same device is rejected...

CVE-2026-74514

Summary of CVE-2026-74514 (Linux kernel, KVM on s390): The issue arises in memory accounting for pinned/unpinned pages where account_mem() and unaccount_mem() call get_uid() multiple times without corresponding free_uid() calls, potentially leaving a reference on the wrong process context. The bu...

CVE-2026-74513

CVE-2026-74513 affects the Linux kernel where a use-after-free can occur in dibs loopback handling due to a race between hash-table lookup and refcount teardown of dmb_node. The fix makes hash table membership and refcount transitions atomic: final refcount_dec_and_test() and hash_del() are perfo...

CVE-2026-74511

A use-after-free vulnerability exists in the Linux kernel's Bluetooth management (mgmt) subsystem . The root cause is a race condition in pending_eir_or_class(), which failed to include MGMT_OP_SET_LOCAL_NAME as an EIR/class-affecting command and walked hdev->mgmt_pending without holding hdev-...

CVE-2026-74512

CVE-2026-74512 is a Linux kernel use-after-free in audit_del_rule() during rule deletion. The issue arises when audit_del_rule() destroys e->rule.exe via audit_remove_mark_rule() before unlinking the rule from RCU-visible lists and waiting for a grace period, allowing concurrent readers in aud...

CVE-2026-74510

CVE-2026-74510 affects the Linux kernel Bluetooth mgmt subsystem. It describes a use-after-free (UAF) in pair command cancellation: pairing completion and authentication failure callbacks could dereference a command freed due to races on the shared mgmt_pending list. The root cause is a lookup th...

CVE-2026-74508

CVE-2026-74508 affects the Linux kernel Bluetooth HIDP path. The bug occurs in hidp_recv_ctrl_frame() and hidp_recv_intr_frame(): they read skb->data[0] before verifying the L2CAP SDU header, enabling an uninitialized-byte use from skb tailroom when an empty basic-mode SDU is received or when ...

CVE-2026-74509

The CVE applies to the Linux kernel Bluetooth HCI path for extended advertising. Root cause: hci_find_adv_instance() can return an adv_info pointer that remains valid only while hdev->lock is held, but advertisement data paths perform lookups without that lock and may retain the pointer while ...

CVE-2026-74506

Summary: CVE-2026-74506 affects the Linux kernel AFS code path, where a race in afs_make_call() between async dispatch and destruction could lead to a use-after-free (UAF) of the afs_call, potentially triggering a crash when handling FS.StoreData data. The root cause described across multiple sou...

CVE-2026-74507

The CVE-2026-74507 vulnerability affects the Linux kernel Bluetooth HIDP implementation. The issue occurs in hidp_get_raw_report()/hidp_process_data() when validating numbered HID reports: a peer can reply with a DATA header and cause the code to read beyond the payload, potentially reading a pee...

CVE-2026-74505

CVE-2026-74505 affects the Linux kernel ALSA: 6fire driver. Root cause: a use-after-free can occur if a pending URB is not freed during early error handling in probe. Fix: the patch adds cleanup at the error path similar to the normal disconnect procedure. Impact and remediation are limited to th...

CVE-2026-74503

In the provided CVE-2026-74503 entries, the Linux kernel ALSA timer issue is resolved: snd_timer_close_locked() marks an instance with SNDRV_TIMER_IFLG_DEAD and a close can leave an object referenced if reopened mid‑process. The vulnerability concerns ALSA timer handling when closing snd_timer in...

CVE-2026-74504

Summary (CVE-2026-74504): The Linux kernel ALSA sequencing timer (SND_UTIMER) can be driven by an unprivileged user to set arbitrary 64‑bit hardware resolution for snd_timer via SNDRV_TIMER_IOCTL_CREATE. When bound to a sequencer queue, initialize_timer() computes tmr->ticks = 1_000_000_000 / ...

CVE-2026-74502

The CVE-2026-74502 issue affects the Linux kernel ALSA subsystem (ump) where snd_ump_attach_legacy_rawmidi() allocates ump->out_cvts and frees it on error via kfree(), leaving a stale pointer. If the endpoint is torn down later, snd_ump_endpoint_free() frees ump->out_cvts a second time, cau...

CVE-2026-74501

CVE-2026-74501 affects the Linux kernel ALSA usb-audio, where create_midi2_ump() stores a back-pointer to a per-interface object in ump->private_data but never clears it or installs a private_free hook. If snd_usb_midi_v2_create() fails, free_all_midi2_umps() frees the object while an already-...

CVE-2026-74500

CVE-2026-74500 affects the Linux kernel’s ALSA usb-audio for RME Digiface. The issue arises when snd_rme_digiface_read_status() reads a four-word status block into an uninitialised on‑stack buffer and, if the vendor IN transfer isn’t negative, copies all four words to status[]. Additionally, snd_...

CVE-2026-74499

CVE-2026-74499 – Linux kernel ALSA USB-audio OOB write . Concrete details across connected docs show an issue in snd_usbmidi_akai_output() where buf_end is computed as a signed int (ep->max_transfer - MAX_AKAI_SYSEX_LEN - 1). A tiny bulk-OUT endpoint can make buf_end negative, and the subseque...
