CVE-2026-64353

CVE-2026-64353 is a Linux kernel BPF verifier flaw affecting ARRAY_OF_MAPS that use a BPF_F_INNER_MAP template. When a concrete inner array with a different max_entries replaces the template, the verifier's const-key lookup nullness elision incorrectly uses the template's max_entries instead of t...

CVE-2026-64353

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...

The vulnerability of the bpf_trampoline_update() function in the kernel/bpf/trampoline.c module, which supports the BPF interpreter for Linux kernels, allows a hacker to trigger a service failure.

The vulnerability of the bpftrampolineupdate function in the kernel/bpf/trampoline.c module, which is part of the Linux operating system’s BPF interpreter support, relates to the execution of operations outside of memory buffers. Exploiting this vulnerability could allow an attacker to trigger a...
