CVE-2026-31740

CVE-2026-31740 : In the Linux kernel, a race condition can occur in the rz-mtu3-cnt counter driver where the shared rz_mtu3_channel.dev pointer is overwritten by the counter and PWM sub-drivers when assigning device pointers for channels 1 and 2. This can lead the counter sub-driver to perform ru...
