CVE-2026-64354

The CVE-2026-64354 entry concerns the Linux kernel BPF component, specifically btf_repeat_fields() handling of user-supplied BTF data during BPF_BTF_LOAD. A malformed BTF can trigger an integer overflow when calculating the expanded field count, allowing a heap out-of-bounds write past the fixed ...

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-2026-64352

CVE-2026-64352 concerns the Linux kernel’s BPF LPM trie: sleepable BPF programs can access LPM map data due to incorrect rcu dereference checks in trie_lookup_elem/trie_update_elem/trie_delete_elem. The issue arises because trie_lookup_elem() uses rcu_dereference_check() with a condition that pas...
