CVE-2026-89906

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-2026-89906

CVE-2026-89906 affects the LoongArch BPF JIT in the Linux kernel. The jump offset calculation for tail calls used a stale prior-pass code stride to derive branch distances, which can produce wrong branch offsets and cause soft lockups when extra JIT passes are triggered. The fix recalculates the ...
