CVE-2026-90312

In the Linux kernel, the following vulnerability has been resolved: bpf: Check load-acquire src ptr type before the load checkatomicload calls checkloadmem before atomicptrtypeok. For a load-acquire that fetches into its own source register dstreg == srcreg, checkloadmem overwrites srcreg's type...

CVE-2026-90312

CVE-2026-90312 affects the Linux kernel BPF verifier . In check_atomic_load(), the function calls check_load_mem() before atomic_ptr_type_ok(). When a load-acquire fetches into its own source register (dst_reg == src_reg), check_load_mem() overwrites the source register's type, causing atomic_ptr...
