CVE-2026-89906 LoongArch: BPF: Refactor jump offset calculation in tail call

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Refactor jump offset calculation in tail call The old macro-based jmpoffset calculation derives the jump distance from a stale prior-pass code stride, which can lead to wrong branch offsets and soft lockups under...

CVE-2026-89905

CVE-2026-89905 affects the Linux kernel on the LoongArch architecture within the BPF subsystem. The root cause is a stack layout flaw : the optional arena register slot is placed above the tail call counter (TCC) context . When arena_vm_start is dynamically enabled, it shifts the relative offset ...
