CVE-2026-64353

CVE-2026-64353 affects the Linux kernel BPF subsystem. The issue arises when an ARRAY_OF_MAPS uses an inner map template created with BPF_F_INNER_MAP; a concrete inner array with a different max_entries can replace the template, causing the verifier to mis-handle nullness of lookup results. The k...

EUVD-2026-48897

In the Linux kernel, the following vulnerability has been resolved: bpf: Keep dynamic inner array lookups nullable An ARRAYOFMAPS can use an array created with BPFFINNERMAP as its inner map template. A concrete inner array with a different maxentries value can then replace the template. After a...

CVE-2026-64291 iommufd: Set veventq_depth upper bound

In the Linux kernel, the following vulnerability has been resolved: iommufd: Set veventqdepth upper bound iommufdveventqalloc accepts any !0 veventqdepth from userspace, with an upper bound at U32MAX. This leaves a vulnerability where userspace can allocate excessively large queues to exhaust...

CVE-2026-64291

CVE-2026-64291 affects the Linux kernel’s iommufd: veventq_depth upper bound. The issue: iommufd_veventq_alloc() accepts any non-zero depth up to U32_MAX, enabling userspace to allocate excessively large queues and exhaust kernel memory reserves. Mitigation/patch: cap veventq_depth to 1 <

CVE-2026-31772

The CVE-2026-31772 issue affects the Linux kernel Bluetooth HCI path. The root cause is a stack buffer overflow in hci_le_big_create_sync where DEFINE_FLEX allocates a stack struct for BIS entries with room for 17, but conn->num_bis can be up to 31, leading to a memcpy that can write beyond th...
