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-2026-64353

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...

In the Linux kernel, the following vulnerability has been resolved: bpf: Allow LPM map access from sleepable BPF programs trielookupelem annotates its rcudereferencecheck walks with only rcureadlockbhheld. Because rcudereferencecheckp, c resolves to "c || rcureadlockheld", this passes for XDP/NAP...

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...

CVE-2026-64350

CVE-2026-64350 describes a memory leak in the Linux kernel USB cdnsp driver. The function cdnsp_alloc_stream_info() allocates stream_info->stream_ctx_array via cdnsp_alloc_stream_ctx() . If a later stream ring allocation or stream mapping update fails, the error path currently frees the alloca...
